I have been designing and making electromagnetic generators for 5 years. The instruments send out a pulsed magnetic field and has worked amazingly better then ordinary permanent magnets. Our applicators are covered with soft cloth and only need to be applied for 15 minutes twice a day or more depending on the problem. We also pay close attention to which polarity to use on the body. This is often overlooked and is very important. I do believe in metals effecting the balance of the body so I wanted to throw out this alternative. The website is http://buryl.com
