Magnetism Summary - Don`t Trust Atoms
... Magnets attract magnetic materials (iron, steel, cobalt, nickel) Magnetism (magnetic force) is a non-contact force, this means that it can act at a distance and can pass through some materials. The magnetic force becomes weaker the farther away you are from the magnet. The magnetic force is stronges ...

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.
