Question

Another method in creating a temporary magnet is by using electricity. This can be done by wrapping an iron nail with a coil of wire. By passing electricity through the coil of wire the iron nail will become a temporary magnet or an electromagnet. The strength of the electromagnet depends on the size of the electric current and the number of times the coil is wrapped around the nail. If the electricity stops flowing through the coil the nail will no longer be magnetic.
