Hello all,
I built an electromagnet with 18 guage enamel coated wire (about 600 feet) around a 1010 steel bar (1 inch by about 10). When I hooked it up it was pretty weak. I wanted to know if it was possible to hook it up to a variable dc power supply. I know my ohm load is about 3.8 ohms. I originally hooked it up to a wall wart with a 20 ohm resistor in line, as to not fry the adapter. I would like to eliminate the resistor all together. Would a 30, 10amp power supply work for this?
Thanks!
Kyle
