I'm using a Eveready 6 Volt Lantern Battery 1209, and unfortunately I don't have a voltmeter to test it at the moment. So, no, I didn't measure it when the wire was connected.
Homework Statement
I'm doing a physics demo, and I've made basic electromagnet using some copper wire, a 6 volt battery, and a carbon steel screw, and I need help checking my calculations because I think the magnetic field for my magnet is too large. I've double checked everything and can't...
