Hi all,
I'm a tinkerer, and don't posess alot of electronics knowledge. I have built a very simple electromagnet being powered by either a 9v battery, or 12v (8 AA). I would like to know if there is a way to keep current flowing into the magnet without the batter getting too hot. I also have a 12v led I'd like to install with a switch to allow on/off function. The magnet works great, just keep getting the battery way too hot.
