a magnet whose coils are cooled, usually with liquid helium, to a temperature at which the metal becomes superconducting, effectively removing all electrical resistance.

superconducting magnetAn MRI term for a magnet whose field is generated by current in wires made of a superconducting material (e.g., niobium-titanium), which has no resistance when operated at temperatures near absolute zero (-273°C, -459°F). Superconducting magnets must be supercooled (e.g., by liquid helium), typically have field strengths of > 0.5T and have a horizontal field orientation, making them prone to missile effect if the magnet is not properly shielded.
