👉 In physics, a superconductor is a material that exhibits superconductivity at high temperatures. This means that it can store and transfer electrical current without losing its magnetic properties. Superconductors are typically found in materials such as copper and silicon, but also in certain rare-earth metals like yttrium aluminum garnet (YAG), which has been used to create a superconductor called YAG-Nb. A superconductor is a material that can exist at temperatures where its magnetic properties
