OMG why do you people jump to conclusions about this medical stuff saying that its stupid? Do you guys even understand EMI fields or just pretend to?
The device creates openings in your body by stretching holes in your tissue which allows contaminants to pass through more easily. Imagine a sheet of rubber with a tiny hole in it. Now, imagine that the rubber sheet has some sand on top of it. Only a few grains of sand can pass through the hole because its too small right? Now, imagine if you were to grab opposing sides of the rubber sheet and STTREEEETCH it out!
What just happened???
A bunch of sand fell through the hole as you stretched it out!! Eventually though, everything settles into an equilibrium and the sand quits falling. So now you have to grab the other two sides of the rubber and and give those a pull.
WOO HOO!!! Bunch more sand just fell through the hole!
Keep doing that and all the sand will make it through.
So, what on earth does this have to do with the circuit the OP posted!?!? Well I'll tell you... The circuit makes a magnetic field, which tugs on the iron in your body, which in turn tugs on your tissues! As the iron gets tugged around, it creates tiny tiny holes for tiny tiny contaminates to pass through. Eventually, all the iron gets lined up with the magnetic field lines though so you have to change direction.
If you don't understand this, go grab a high school physics book. If you still don't get it, go hang out at car forums.
