EMF pump circuits are devices which are popularly used for the purpose of identifying paranormal activities or entities by generating rapidly rotating magnetic fluxes in the ether. The conventional devices use a spinning magnet fixed over a motor spindle, however these are mechanical types and are prone to wear and tear.
Introduction
The explained circuit is a solid state version of the above, more reliable with its operations and very effective with the forbidden tasks.It is said that paranormal entities become more energetic in the presence of strong electromagnetic zones, especially when the magnetic fluxes are rapidly varying in nature.
The magnetic fluxes enriches the existence of a paranormal being such that its presence becomes aggravated and quickly traceable using ordinary equipment like RF detector or EMF sniffers.
The presence of the paranormal being enhanced in such a manner makes animals particularly very uneasy, especially animals like dogs would instantly get hyper under such conditions.
The circuit can prove to be an excellent EMF pump device for immediately tracking ghosts and other supernatural activities.
Simulation and Working
The figure shows a circuit design built around the versatile IC 4017 which is a divide by 10 Johnsons decade counter IC.
You can learn more about this IC and its pin outs in one of my earlier posts, comprehensively explained about its installations in a circuit.
Basically a clock pulse fed at the clock input of the IC activates its outputs to go "high" in a sequencing manner from the first to its last pin out in the order.
Using IC 4060 as the Oscillator
The oscillator IC 4060 is configured as a clock generator and supplies the required clocks to the IC 4017.
Here we have used only three of the outputs because only three electromagnets have been involved.
In response to the applied clock pulses, the output from the IC move sequentially across the three outputs rapidly, cycling around as long as the clocks are being fed.
The outputs are applied to power transistors which in turn are connected with strong electromagnet assemblies.
When the outputs of the IC sequence, the transistors also switch sequentially, triggering the electromagnets in a cyclic motion.
The rapid switching of the electromagnets in a rotational motion generates a high power magnetic influx sufficient to invite the "uninvited" in the zone.
The power to the unit should be preferably taken from a 12V 1AH battery source.
For tracking paranormal activities, you can use this circuit in conjunction with the ghost detector circuit explained in one of earlier posts, together the devices will produce pin point results.

In the circuit of the emf pump there are 3 diodes in parallel at the inductors, which are not mentioned in the list of components. That diodes are? Thank you
Swagatam says
you can use 1N4007

I'm trying to find a device or plans to build a device that will generate random EMF noise in the frequencies of 30 Hz – 100 Hz with an adjustable output of about 10 mG to 50 mG. The purpose is to disrupt the cellular oscillation caused by a constant 60 Hz high EMF in my house. Anyone have suggestions?
Swagatam says
It can be done using a single 4060 IC, I'll try to present it in my blog soon.
thanks!

so.. you are saying that this circuit will scar away the ghost from the infested area…
am i right?
thank you.
Swagatam says
Oh yes, but only if the frequency is correctly optimized, otherwise it might do just the opposite.

hi sir. i understood this circuit. but i don't know how to use this circuit. can you tell me how to use it.
Swagatam says
use it for deterring the ghosts that may be present in the infested zone.

Hello!
I'm gathering the parts to make the EMF pump soon
The electromagnets, can they be purchased? or is necessary to make them by hand?
www.e-merchan.com/pub/kic6092.pdf
Swagatam says
Hi,
If you can get the EMs readymade it would be great as you would provide you with a precise thing, if not then you can make it manually by winding the required number of turns over an iron core.
Borja Wolf says
Thanks friend! 🙂

Ok excellent 🙂 dose it make an electromagnet as such, can I tell its working via some metal attracting to the coils as such? I'm not 100% I have it going yet, as none of the 122s are getting hot. Then maybe I should leave it on for a period, as you can tell im no electronic wiz haha. Ill upload the link shortly.
Swagatam says
oh yes:) you can try putting some iron pins over the electromagnets, if the pin start vibrating would indicate the proper working of the circuit, however as you say the transistors are not getting hot, I doubt if the circuit is really functioning, because the process should make the transistors hot;)
Anonymous says
Hi there and thank you for this post! Just verifying with the transistors..is the following correct base=resistors emitter=negative and collector=coils/positive. Should there be a magnetic field coming from the hand made coils, I don't have a meter to detect EMF…atm anyway. I can post a picture if anyone is keen to see what I have done.
Dan.
Swagatam says
yeah, that's correct.
once the circuit is switched ON, the connected coils will start generating high frequency pulsating electromagnetic waves, which may be useful for detecting or rattling a paranormal presence.
Swagatam says
you can upload the pics to www.imageshack.us and give me the link, I'll update it here.
James Carter says
Thanks Swagatam!!
question:
Been doing some research on electromagnets and their function, the way i saw was with one wired (coiled) with one end connected to the positive side of a battery and the other end connected to the negative side. Now im not the smartest man in the world but i always thought it was bad to touch the two leads together, i mean it is basically taking a 12v car battery and dropping a metal wrench between the two poles? I take it this is why the coils get hot? This circuit allows pulses so it isnt a continuous drain on the battery?
In the diagram you show there are 3 wire leads coming of the electromagnets,would those connect only the positive sides of the transistors? Im a little confused on that part.
Swagatam says
You are right James, with inductors or coils, DC supply is strictly a "NO", they work only with ACs (alternating current) or pulsed DC, meaning the supply across the coil should be alternating or in a pulsed form.
The transistors shown in the diagram act like switches which turn On/OFF many times a second as per the setting of P1.
One wire from all the coils are made common and connected to the positive, the remaining separate ends of the individual coils are connected with the respective transistors. So now when the particular transistor pulsates it connects the relevant coil with ground in the process (because one end of the coil is already fixed to the positive)
In this way the coil connects and disconnects alternately with the ground via the transistors and this generates the required magnetic field across the coils.

hello there, love the site so far!
I am James founder of P.R.O.U.D Paranormal

I have been looking for a schematic for this for sometime now, i have built the motor type em pumps but found that they are not practical for investigations do to the noise they generate.
I am not the greatest with electronics but i am learning on a Radio Shack electronics learning lab.I do have some questions:
Does pot =potentiometer?
Carrying around a twelve volt battery on investigations does not seem practical, would this circuit work via 18v (2-9v wired in series?)would i have to change the circuit at all?
The symbols on the diagram next to each transistor, are those the electromagnets?
Any help will be appreciated and thanks for a great site!!

Swagatam says
yeah…pot = potentiometer.
the parts connected to the transistors are electromagnets.
a single 9V cell will also do, however I doubt if the current would be enough for driving the EMs.

Hi there! I have been looking for an em pump schematic for some time now and finally found one. Love the site. I am the founder of P.R.O.U.D Paranormal. I have built the mechanical em pumps but found them to be not practical due to noise. They contaminate audio during investigations. I am not the best with electronics, I do have a radio shack electronics learning lab and that has been helping me. I do have questions about your circuit, What is a POT, and what is its functions? Your circuit is for 12volt if I changed it to 18 volt (two 9v wired in series) would I have to change the circuit? Any advise would be appreciated and thanks again for a great site!

Swagatam says
Thank you James.
The pots are variable resistors, whose resistance can be varied manually….this adjustment can be used for correspondingly changing the frequency of the EM connected at the output.
The ICs can tolerate at the most 15V, so 18V would be too high, so its not recommended…
Regards.

I have questions on the parts list for the emf pump circuit above.
R1 = 2M2 – Is this simply a 2 Megaohm resistor? Why is there another "2"?
For T1, T2, T3 = TIP122 – Is TIP122 actually a part number/identification for the transistor? Is it a BJT as the schemetic indicates? Most BJT's that I know of you can't fit a heat sink on to them as they are too small.
For each electromagnet in the circuit above, there is a diode in parallel with each electromagnet. What purpose does the diode serve and why aren't they listed in the parts list? What would be the diode part number? If these are suppose to be LED's then the wrong reference designator symbol is being used here.
For the 12V battery – What does 1AH stand for? Is it 1 amp hours? Could two 6V lantern batteries connected in series work also?
Swagatam says
R1 = 2M2 = 2.2 Megaohm or 2200K Ohm
TIP122 is the actual part number that will be seen printed over the device. It's a Darlington Power BJT, TO-220 package, has a metal tab and hole for fixing heatsink.
The diode are positioned for shorting out the reverse back emf from the coils. This protects the transistors from the coil back emfs. These diodes are called freewheeling diodes or flyback diodes.
However these diodes are not required for TIP122 because a TIP122 already has a similar inbuilt safety diode.
AH = ampere hour, two 6v batteries in series will do, but should be minimum 1 AH rated each otherwise it will drain out quickly.
Barry says
Thank you so much for the information.
I have a couple more questions then:
Do you know of any example part numbers of the freewheeling or flyback diodes or will any diode do for hooking up in parallel to the electromagnets?
Since emf will be generated by the electromagnets, is there a distance requirement for the solid state portion of the curcuit that contains the clock generator and Johnsons Decade Counter or is there a potential of these devices getting damaged by the emf generated by the electromagnets?
Swagatam says
Any rectifier diode will work here….a 1N4007 would be quite enough.
The emf generation will not affect the ICs at all, you may keep all the components on a single PCB close by.

One reason your transformer is drawing so much current is that you are saturating the core. This is called the S curve or hysteresis of a coil.
You could drive the coil the same way, but place a capacitor in series with the windings. This would act as a current limiter and when the coil goes into saturation, the cap would charge up, rather than having the coil draw alot of current.
Another way would be to place a small value resistor in series with the coil, although the drive current would be reduced.
There are other ways to limit the current dynamically in the drivers.
crispy critter says
I have got to a more stable and efficient coil. I have used a 90 pound magnetic pick up solenoid. It was able to hit 18,000 mG drawing less current than my hand made coil. I built the 3 channel EM Pump still using a 555 timer instead of the 4060 Here is the video….

So after long time inactive. I was able to test my single coil EM pump at Hales Bar Marina. I captured an EVP saying "I'm over here". If you ever seen Ghost Adventures, where Aaron was touched on the catwalk. That was where I had the pump. It ran in 80 degree temps for about 3 hours. The casing was pretty warm but still functioned. The power supply was a lawnmower battery My father left his camcorder on his tripod and the EM pump was about 15 feet away.. While walking back to retrieve the gear we had swarms of bugs. We had ton of spiders all over the place. I saw the spiders first and kind of figured there was an explanation for all of the spiders, like flying insects… We went from having no flying bugs (mayflys) for 6 hours of the overnight investigation. To hundreds of thousands of Mayflys, almost on biblical scale. Just out of curiosity I did ask "If any spirit or entity causing the swarms of bugs". I didn't capture anything on my camcorder, nor my recorder. However after reviewing the footage about 30 seconds of me asking that questions I get "I'm over here" on my father's camcorder audio. I caught a few more EVP's and spirit box sessions mainly in the executive suite and the "crazy room" Interesting experience. Haunted? Don't know really. I have to have more than audio to say yes. I got one cold spot 3 times in "Mary's room", which is actually an opening at the end of the tunnels and a reading that fluctated from .1 to .8 mG. Also having a rather large group I had to rule out a lot of stuff through the walk through. That and also a bunch of drunk people singing "Brown eyed girl" outside in the other active parts of the Marina….
I've got a friend that is letting me do a few hours in a recently opened seafood restaurant that supposedly has a black mass in it. Maybe be able to try it again there .

Thanks for the info Dany…Good luck to you.

Can the PCB ARtist idea i printed and scanned the image
Swagatam says
I got the image…. checked and have replied the email.
John Murphy says
hey buddy have sent you a copy of the PCB layout which can be opened in "PCB Artist"
what look like coils are the Electromagnets on a PCB and not wood
Hopefully you will be able to open it
John Murphy says
Well no actually, still looking but have had good images and evp sessions.
Now I used an LED as a test light and got it flashing at the 100k pot so its obvious the 4060 is working although there is no increase in flashing speed. I am going to attempt to build another. I wish I had a way of sending you a copy of the PCB diagram so you can look at it and see if i haved stuffed up somewhere
Thx John
Swagatam says
OK great!
I think you should have connected leds in series with R4, R5, R6, that would have given you a clearer idea regarding the functioning of the whole circuit.
You can mail me the diagram at hitman2008@live.in, i'll check it out
Regards.
John Murphy says
Yeah I am a ghosthunter swaggie Check out Shadow Riders Paranormal Investigations on Facebook in Australia
Swagatam says
Wow! that's interesting, did you catch any so far..??
John Murphy says
well i have just finished making this and held an EMF meter to it and no readings on the meter at all. Where have I gone wrong????????
Swagatam says
Connect LEDs in series with the bases of the transistors, Vary P1 clock/anticlockwise, if the LEDs responds accordingly and show a varying sequencing speed, then you circuit is OK and is working perfectly, if one of the LEDs stays stationery while the others remain shut off, would mean there's something wrong with the oscillator section and the circuit is not working correctly.
Swagatam says
By the way are you a ghost hunter??

crispy critter says
Well I have found if I uses a smaller gauge magnetic wire (Red spool from RadioShack) and use a 5/16x 2 1/2" bolt and nut I get a good response. The coil still gets rather warm. I've thought about drilling holes in the top and bottom of the case for cooling. I haven't really counted how many times I've wraped the bolt. I do believe metering the leads from the magnet was about 8k ohms. I found out the freqeuncy the circuit as a big influence on the magnetic field strength. I can use the pot and LED to see how fast the circuit is switching. While on a low setting it will turn on for a few seconds and shuts off. Probably 5 seconds on and off. I can get a reading of 20mG. If I bump it up to almost constant my MEL meter pegs out right next to it. Switching from the 200 mG range to a 2000mG range. I have about a 1546mG reading using a 12v 1.3 amp drill battery. I have thought about grabbing 2 more bolts and wrap them as well. Wire them in parallel with the orignal electromagnet and see if that helps increase the field strength. I have used MSpaint to put together a real basic version of the circuit I've modified. My plan eventually is actually build your circuit on a larger scale. I've thought about building 3 seperate magnetic boxes with a lead of a few feet. Having the main unit next to a power source (vehicle or lawn mower battery), and have the magentic boxes out in a y shape. Making a very large vortex. The pot would be used to adjust the cycle rate. I am also researching " Schumann Resonance". If you haven't heard of it, I would suggest you read into it. If you want to updated your blog or use this picture for anything, I give you my consent to use it tinypic.com/r/3130f38/6

Would it not be better to use a MOSFET than that transistor? And a ferrite ceramic core that can gain and loose a magnetic filed faster than can iron or steel? and how did you claculate the coil or did you just guess? is 8kohm a typo? that sounds like a lot for a coil that size. 8ohm sounds more like it.
Swagatam says
You are correct, ferrite works better at higher frequencies than iron core which might become too become hot just like an induction heating
Anonymous says
What about swapping the transistor for a MOSFET? Would his circuit be able to turn it on and off? If so, and providing the MOSFET can turn on and off as quickly as the circuit demands of it, then I see no reason not to make the replacement. MOSFETS can handle more current and are more efficient.
Anonymous says
What about using a MOSFET? Would his circuit be able to turn it on and off? And would the MOSFET be able to turn on and off fast enough? MOSFET's handle more current and don't waste as much energy
Swagatam says
mosfets are better than transistors no doubt, it can be used here for better efficiency, however transistors are also rated to work at much higher frequencies, so either will work, depends on what you have in hand.
Anonymous says
Sorry to double post i did not think it was successful posted the first time. suppose I want to go no higher than mains frequency say 50 hz or maybe a little higher would mosfets then be a better choice. I would think the time taken for the core to reach saturation would be more of a limit factor here than is the speed at which the mosfet/transistor can switch? is that right? How fast could you turn a mosfet on and off anyway? and where to find how to make the changes to YOUR circuit to get different frequencies? I find plenty of online calculator that work with 555 timers. Actally what is s the frequency range of your circuit?
Swagatam says
mosfets and BJTs are both like switches, capable of switching frequencies right from 1Hz to Mhzs, so the switching speed is not a concern here for both the counterparts.
The diodes placed across the coils will desaturate the coils as quickly as they saturate, so that it's always ready for the new pulse.
In the above design, Pi, R2 and C1 together and individually determine the frequency rate, you can tweak them to get any desired frequency as per your requirement.
crispy critter says
So I tried to initial design and had problems. I got the 4017 to light up test LED's at first But couldn't get the 4060 to trigger the 4017. So I decided to fall back on the 555 timer which would work fine. I ended up trying serveral schematics but had problems still not triggering it. So I found a project I worked on a few months a go and used the "555 Police lights" from
talkingelectronics.com/projects/50%20-%20555%20Circuits/50%20-%20555%20Circuits.html#56
I used the 555 timer portion but instead of using a fixed Resistor value for the 22k resistor, I used a 100K pot. Instead of trying to try triggering 3 transistors I simplified the circuit only doing one. So far I've finally got it working. I've added an LED between the timer and transistor for a visual. A lot of this was circuit bending and guessing. I am pretty much noob to this stuff. Results are good. Magnets get pretty warm. Still testing it out.
crispy critter says
Correction. I have found that this puppy will produce 3300mG
MattF says
2 questions: your pot just lists as "100pot", what is the value you used? and 2: how much of a coil did you create for each of the electromagnets? (IE: guage wire, length of core, #of wraps) Thanks.
Jason says
also will the TIP's get hot in this circuit as well?
Jason says
could it be made to run off 6v?
Jason says
does this pulse?
