I have constructed a DC electromagnet for a special use at my shop. Being a
electrical contractor I thought this would be simple. (NOT) Made the
electromagnet, connected it to a 12vdc power supply at 5 amps and it works
great with one problem, it starts to heat up quickly. My desired results
was for it to run on a 80% duty cycle. Will resistors keep this heating
problem from happening? DC voltage is not something I have dealt with
indepth. Can anyone help me with this problem?
