Do It Yourself PEMF system

As mysterious and complicated as PEMF device manufacturers wish it to sound, Pulsed ElectroMagnetic Field, in essence, is just an electronic system based on simple physics – i.e., when the electric current is passing through a wire, a magnetic field is created, circling the path.  By time varying the current passing through the wire, you get a pulsed electric magnetic field. Not a rocket science, despite “NASA research” was always being referenced. What matters, of course, is in the details, like the intensity, frequencies waveform, and also the material and design of the applicators. All these contribute to the effectiveness of the system design. Similar to an audio system – anyone can make a sound system with off-the-shelf components, and get it to produce audible sound. However, to perfect the sound, it takes precision and experimenting, and the right parts. And that’s what set apart various PEMF manufacturers and products available in the market today.

As the affordability of a full body PEMF devices today are still beyond a reasonable reach for many people, what we would like to share with everyone is how easy and affordable it is to assemble a simple PEMF system using an audio player with an easy to order component. Being able to create your own PEMF device does not negate the value of a well designed, proven and safe PEMF systems you can purchase from the market today. Instead, this is purely an exercise for you to experience the PEMF and appreciate the intricacies and the knowledge behind the entire treatment modality. Unless you are with an electrical background, else we do advise not to experiment with any PEMF system with an amplified (high-voltage) system without knowing what you are getting.

As mentioned in my previous post – Micro-Pulse today is offering one of the cheapest and affordable PEMF devices in the market for localized treatment. At just USD 429, you can get a fully functional ICES PEMF portable system running on 9V battery, which comes with three pre-programmed programs. If you visit the product website, you will also realize they are selling the replacement coil starting at USD 20 with free shipping! Micro-Pulse is one of the very few PEMF manufacturers that I come across who priced their parts at a wholesale price – good news in fact for our purpose here. The other PEMF manufacturer is EarthPulse, with its entry level EarthPulse Sleep-on-Command Basic selling at USD 499, giving you the possibility of adjusting the frequency from 0.1 – 14.1Hz at 0.1 increments. Another excellent product for experimenting the effect on different frequencies.

Now what you will need is simple

  • Order a pair of replacement coil from the MicroPulse Site. It comes in 2 lengths. Order a long coil 47″ instead of 12″.
  • Download a pre-generated audio-version of PEMF files and copy to any of your audio players. Here we have prepared a simple 9.6Hz variant (between 9.1 – 10.1Hz with 9.6Hz as the base frequency) for testing using .mp3 format. Recovery 9.6Hz (mp3 version). Read more about 9.6Hz recovery mode by EarthPulse. You can also create your version here
  • Ideally, you can also get a standalone EMF tester, but no harm testing out EMF software version using your Smartphone.
  • Simply launch your music player – choose the PEMF audio file and play. Make sure you have only one single file in the playlist – so once the session is completed, it will not automatically select another soundtrack to play – which will generate unwanted frequencies that you won’t want to expose. You can play the soundtrack in repeat mode. The soundtrack is programmed in such a way that it runs between 9.1 and 10.1 Hz, with primary frequency set at 9.6Hz. Usage time recommended no longer than 30 minutes for a start.

The principle behind this is the audio player itself is essentially a pulse generator, capable of generating time-varying voltage/current to the speaker, which in turns generating magnetic pulses that drive the speakers. By replacing your speaker with ICES Magnetic coil (note that your speakers are in fact a magnetic coil with a cone to reproduce the sound), you are using your audio player as the pulse generator of PEMF, with the desired frequencies and waveform. However, do note that the voltage able to be delivered by a typical smartphone is probably less than 2V. Nevertheless, this should give you some fun in experimenting the PEMF technology without breaking the bank.



  • PEMF.SG does not claim the effectiveness of the quality of the PEMF generated using this method.
  • The quality of the waveforms generated may be influenced by the quality of the audio decoder, lossless (.flac) or lossy (.mp3)  file format and the magnetic coil you use. If possible, we do suggest use FLAC or ALAC (apple lossless format). There is no guarantee that you will get the exact precision you programmed in the audio file, though they should be pretty close. The best way is to test the final output using an oscilloscope with a magnetic sensor, but this is probably beyond the scope of our intention here.
  • Also, we cannot assure if there will be any damages caused by inserting the ICES Coil into your player audio jack after all your audio jack is meant for your speaker or headphone. We have tested the ICES coil with a different type of audio players (laptop, mp3 player, smartphone, etc.) and so far we have no issue with this. However, the advise is don’t try this on an high-end or expensive audio player. You can obtain a cheap .mp3 audio player at USD 20 or below from many online stores.
  • If you are creating your soundtrack for PEMF, our advice is to keep the frequency range within 100Hz, ideally between 0-30Hz.
