I am making an electromagnet that will have a pack of AA batteries powering it.
Sounds cool.
I expect it provide 30-40 amps
Wait, what - ?

That's not true, with the diode in place the maximum voltage will be the forward voltage of the diode.However the reverse voltage rating should be looked at closely as the fly back pulse can reach 4X the coil voltage rating.
