... If a bar magnet was broken in half, it would create two magnets each with their own north and south pole. If the process continued, breaking each magnet in half until it reached the size of one atom, the atom would have a north and south pole. This demonstrates that atoms themselves can be a magnet. ...

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.
