Boaz Almog: The levitating superconductor

The video explains quantum levitation and quantum locking using superconductors. It describes the properties of superconductors, such as zero electrical resistance and magnetic field expulsion. The concept of quantum locking is demonstrated, showing how superconductors can be locked in place within a magnetic field. The video also explores the potential applications of superconductors in technology, such as in MRI machines and energy storage, and speculates on future advancements.

What are the two defining properties of a superconductor?

• High temperature stability and magnetic field absorption

• Zero electrical resistance and magnetic field expulsion

• High electrical resistance and magnetic field attraction

• Low electrical resistance and magnetic field attraction

What happens to magnetic strands inside a superconductor under proper conditions?
