the nature of the problem that I am trying to solve has to do with the strength or electromagnet in relationship to their size and what affects a magnetic can have on the human body. For what I have seen, the power of an electromagnet seems to be related to its size (like the ones in a vehicle wrecking yard). I am interested the scalability to powerful magnets. In other words, how small can an electromagnet be and still maintain a force strong enough to move or influence body parts?
Yes- in a way. So for instance- if I have two electromagnets- one on the forearm and the other on the upper arm, I want to coordinate the electromagnets to attract or repulse to move or influence the elbow joint.
