Superconducting magnets are used in machines called particle accelerators. These machines rely on zero resistance in order to function properly.

How are the magnets able to have zero resistance?

They are heated to extremely high temperatures.
They are cooled to extremely low temperatures.
They are made to be very thick.
They are made to be very thin.

They are cooled to extremely low temperatures.

Explanation: Superconductivity — the state with zero electrical resistance — occurs when certain materials are cooled below their critical temperature (and kept below their critical current and magnetic-field limits). Accelerator magnets (e.g., Nb–Ti in the LHC) are kept in cryostats at a few kelvin (often using liquid helium) so the coils become superconducting. Thickness or thinness does not create zero resistance, and heating would destroy superconductivity.
