Question

Why do superconductors make magnets float in place at extremely low conditions?

Answer 1

This is because when those materials are cooled to extremely low conditions, they are able to manipulate the magnetic fields of magnets, and conduct them with almost no resistence.

The magnets simply float in place because of something called flux pinning where the superconductors leaves thin threads of magnetic field to hold the magnet floating above it in place. This is due to defects and inpurities in the superconductor. However, the magnet can be moved by force and spun around freely if the superconductor is big and strong enough.

However, the moment it gets too warm, the material loses its superconducting ability almost instantly.

I hope this helped!

Answer 2

Any magnetic fields that were passing through must instead move around it. When a magnet is placed above a superconductor at critical temperature, the superconductor pushes away its field by acting like a magnet with the same pole causing the magnet to repel, that is, “float”—no magical sleight of hand required.
