What is a superconductor? | Live science

A superconductor is a material that achieves superconductivity, which is a state of matter that has no electrical resistance and does not allow the penetration of magnetic fields. An electric current in a superconductor can persist indefinitely.

Superconductivity can only normally be achieved at very cold temperatures. Superconductors have a wide variety of everyday applications, from MRI machines to super fast maglev trains that use magnets to levitate off-track trains to reduce friction. Now researchers are trying to find and develop superconductors that operate at higher temperatures, which would revolutionize energy transportation and storage.
