Dear Forum,
I am attempting to make a treatment mattress or pad for PEMF treatment of osteoporosis. I have osteo, and there are commercial units available, but they cost ~$3K+! I have a capacitor discharge circuit, but need a coil design for the pad. I created a gauss probe with a linear hall effect, and can measure the desired levels on my PC Scope. I wound a flat circular coil, and see that the desired levels are present. The coil is wound all the way to the center. Over the center the field is quite strong, and tapers off as the probe is passed from the center to the outside edges.
Would a flat ring coil design, with a large open center work better? Or one with a certain size open center? I wish there was a free fea program that was easy to use available, but I cannot find one. Any guidance would be greatly appreciated!
Mike
