This first post is going to start with how to build a simple PEMF device. No introduction on why you would want to do this, or the benefits of the device, that will come later, or you can search the web for this information. The device is simple – you need an MP3 player, an electromagnet, and some MP3 files that contain a signal that will generate a healing and beneficial pulsed electromagnetic field from the electromagnets.
These magnets are found on the internet for between $20 to $30 US dollars, and go by the name Alleva-Wave Replacement coils or SomaPulse Replacement coils (See note below dated Aug 12, 2015). They have a plug you can put into a headphone jack of an MP3 player. I found some on Ebay that were $23 USD including shipping.
Ideally you already have a device that can play MP3 files. This could be a dedicated MP3 player, a computer, tablet, or phone. If you have none of these, you can take the MP3 files and burn them to an audio CD.
Whatever MP3 player you have, there are 2 important features that are necessary. The first is the ability to plug it into your wall power while playing, as you will want to use this device for long periods of time, and this will drain batteries. The other feature the player needs to support is repeating a song over and over, a single song repeat mode.
Download the MP3s that are in later posts, load them to your MP3 player, put the player into repeat mode, plug the coils into the headphone jack of your MP3 player and play. For these particular coils, its best to have the smooth side of the coil facing your body. The next posts describes the various set of MP3 files that are useful for better sleep, pain relief, and improved circulation.
The Downloads are offered in three different audio file formats. For Apple and iOS products (iPod, iPhone, iPad), choose Apple Lossless (ALAC). For open source music players, like Android 3.1+ and Rockbox, or commercial players like RIM Blackberry, Cowon, Creative Zen, HiFiMAN, Sansa Clip family, TrekStor, iRiver, Archos, and Latte, choose Free Lossless (FLAC). If your music player cannot handle the other lossless formats, choose MP3, which is a lossy format. The ALAC and FLAC formats will offer no distortion and smaller download size, while the MP3 files are distorted because of the lossy compression.
[Aug 21, 2015 Update] The Alleva-wave and Somapulse products have been taken off the market by their parent company, Micro-Pulse LLC, and are now marketed under the Micro-Pulse label. To buy these coils, go the Micro-Pulse website and buy the replacement coils for the Micro-Pulse product.
