Okay, I have been looking the web over for some toroidal (doughnut) electromagnets for a project I am working on. Any ideas on where to get some? I need about 8 to run off of 110 VAC (10A) or 12 VDC (220A). Inductive force is not important. Inner OD should be about 3 inches or so. Danke (no umluat, can't find char map, grrr...).
