... Ferromagnetic materials are made up of regions known as domains. Within each domain, the magnetic fields of all the atoms are lined up in the same direction. When exposed to a magnetic field, the domains tend to line up with the field. Due to the existence of domains, ferromagnetic materials are eas ...

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.
