first of all i would like to appologize if this is in the wrong place. That said, I need help building 2 small opposite pole electromagnets to move a pair of small rare earth magnets back and forth approx. 1-2 inches along a rail.
|e-mag1| -rail--|perm.mag|--rail--|e-mag2|
|<------approx 1.5"------>|
the rare earth magnets I've been using are 4lb pull and 8lb pull. (sorry that's the only info i have on them)
unfortunately, the amount of space i'm limited to is a hollow cylinder 1.5" Inner diameter and about 8"long. and i need the e-magnets to run off a pair of 9v or a couple AA/AAA batteries.
I've been tinkering for a couple weeks but have been getting nowhere. any help would be greatly appreciated.
also, what would be the best type of wire to use for the coil? i have a lot of 20awg copper, silver, and stainless.
for the uninsulated wires, what would be the easiest way to insulate them. time is no concern since i have it in abundance.
thanks in advance for any help.
Joe
