Yeah... my father called it nichrome... right after I bypassed the wiring harness on the Buick hit-to-pass race car I set up... had to pull as much as I could of that wire out of the harness and wire it back in. Never did understand why it had to be there until I read this thread. Makes sense now... thank you.
As for the heating bit... power out is volts * amps... a couple of volts drop on the minor current a coil would draw isn't going to amount to much power and thus heat.
