What is a magnet?
... magnetic effects in matter are the electrons in atoms. There are two ways in which electrons create magnetism: 1. Electrons around the nucleus and their motion makes the entire atom a small magnet. 2. Electrons themselves act as though they were magnets. ...

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.
