Jeff Behary's Electrotherapy Museum Full of Restored Tesla Coils

@kryptik: I'm so happy that I saw this. I was reminded of what I wanted to ask you a few weeks ago. How much do you know about the mathematics behind electromagnetism. I'm specifically interested in the superposition of (electro) magnetic fields. Is this cumulative? also at what distance would this not be feasible if I'm powering small coils? What level of precision could I expect to achieve? (Hoping for a mm or at around 1T.)

@speciousxx: Have you seen the old 80 90s videos from Borderland Sciences (Eric Dollard and co)? They also did a whole magazine and video reviewing all the past health technology, pictures and all. I think they might have been at a museum or via their own collection. replied to 0:01 on 3speak.tv
