Hi
There are no Electro Magnetics invoved in RIFE euipment, it is sound and ultra sound only. The BECK MAG pulser uses EM in very short bursts, I do have one of those machines and it is nothing to do with RIFE.
The sound wave is either delivered through the air using a neon/argon type tube or by direct contact with a pad. The sound waves pass right through walls as well as anything in it's path. A bit like your radio.
