... How does electricity flow in an electromagnet? The electricity flows through the wires that are hooked up to a D-cell starting by going out the negative and back into the positive terminal. It also flows through the switch if it is in the closed position. In an electromagnet, if two rivet heads come ...

Superconducting magnet
A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic fields than all but the strongest electromagnets and can be cheaper to operate because no energy is dissipated as heat in the windings. They are used in MRI machines in hospitals, and in scientific equipment such as NMR spectrometers, mass spectrometers and particle accelerators.
