... Any magnet, no matter what its shape, has two ends called poles. A pole is the area of a magnet where the magnetic effect is strongest. One pole of a magnet points towards magnetic north of the earth and is labeled north. The other pole is labeled south. Although magnetic forces are strongest at the ...

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.
