hi everyone, would like ideas/help for a simple if possible 12v circuit that i can use to switch poles on my electromagnet for a demonstration electric motor. i don't know the amount of winds or wire size(looks like 2mm)has a resistance of 2.7 ohm's. i don't mind if it overheats a bit as I'm going to use it for short periods of time only. I've been using the electromagnet on a 12v 2.5amp,hr battery, but i need it to switch poles with variable speed control would be nice.
i have (if it helps) a few bc337,2n3055 and a mje3055 transistors handy.ill buy if needed of course.
appreciate the help.
