LAB: Building the Best Electromagnet
... current-carrying wire is generally very weak. One way to increase this force is to increase the current in the wire, but large currents can be fire hazards. A safer way to create a strong magnetic field is to wrap the insulated, currentcarrying wire into a coil. This current-carrying coil of wire is ...

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.
