Copper- or aluminum-based electromagnets with fields larger than 10 Tesla are large devices with huge consumption of electrical energy. The record copper magnet reaches the magnetic field of 36.2 Tesla with 19 MW energy input. For comparison, the electric energy consumption of the 32 Tesla HTS magnet is three orders of magnitude lower, being only 50 kW.

Superconducting magnetic energy storage (SMES)
Low temperature superconductors such as NbTi or Nb3Sn are widely used to make large and efficient magnets. The well-known examples are MRI systems and Large Hadron Collider. 2G HTS tapes possess very high critical field values, virtually in excess of 100 Tesla. This performance significantly widens the window of attainable magnetic fields as compared to low temperature superconductors. With the use of HTS, the fields of tens of Tesla can be reached at temperatures higher than 4K, significantly decreasing the necessary refrigeration costs.
