Question

How does a liquid nitrogen levitation take?

Answer 1

Hello friend
Liquid Nitrogen is very cold in nature its boiling point is -192°c approximately.

When a soft metal core (conductor) is made superconductor with the contact of liquid nitrogen. Then if the superconductor is placed over a strong earth magnet then the superconductor levitates.
it will levitate till the conductor is superconductor when the super conductor becomes normal conductor again then it will fall back again.
०Here is its phenomenon

Superconductors expel magnetic field, and hence repel magnets. This repulsion can be stronger than gravity, which leads to levitation.
