Question

How do you make an electromagnet with a battery?
1.2. Why does the nail have magnetic properties?
1.3. What happens if the battery is removed?

Answer 1

Use a pair of wire strippers to remove a few centimeters of insulation from each end of the wire. Neatly wrap the wire around the nail. The more wire you wrap around the nail, the stronger your electromagnet will be. Make certain that you leave enough of the wire unwound so that you can attach the battery.

1. The properties of these magnets as stated above is due to the action of the spinning electrons in atoms. Groups of atoms join in such a way that their magnetic fields are all arranged in the same direction. ... In the case of a nail, the domains can be aligned in the same direction causing the nail to become magnetic.
2. When the battery is disconnected, the magnetic field goes away, and the nail no longer acted as a magnet.
