Hi!
I have bought two electromagnets 12V. I wanted to try them by connecting on a simple 9V battery. The guy who sold me the electromagnets wrote me " Don't forget the back emf diode". Now that I know what a back emf is, I'm afraid to try my electromagnets.
Can I plug the electromagnet directly to the battery without any damage for me and/or the battery or I need to make a circuit with a transistor and a diode?
Thanks!
