Core with windings in both directions??
Core with windings in both directions??
(OP)
I'm no electromagnet expert and I was wondering if the following idea would work.
If I wound a core one direction, and halfway through, started winding in the other direction, could I create a usable electromagnet where the poles are the same on both ends?

All that happens is that the magnetization effect is cancelled out, assuming that you have the same number of turns in each half.
This sort of thing is used to build non inductive resistors...

Putting two electromagteic this close would produce a tremendous force on the bars/windings. I think you would stretch the bar and probabaly rip the winding off as well. So having thought it through, my answer is also NO
