Question

What is the value of susceptibility of a superconductor?

Answer 1

Answer:

Superconductivity is a set of physical properties observed in certain materials where electrical resistance vanishes and magnetic flux fields are expelled from the material. Any material exhibiting these properties is a superconductor.

Answer 2

Answer: The value of susceptibility for a superconductor is -1.

Explanation:

Susceptibility here means response to the provided field which may be an electric field or a magnetic field.

A superconductor is a material that has no electrical resistance which means electric current can persist in it indefinitely and does not allow a magnetic field to penetrate it.

Superconductors oppose magnetic fields, which means they are perfect Diamagnetic material.

The formula for Magnetic susceptibility is:

$X_{m}=M/H\\Where,\ M=Magnetization\ \\ H=Magnetic\ field\ strength$

The value of magnetic susceptibility for a diamagnetic material is always below zero, and since superconductors are perfect diamagnetic, The value of magnetic susceptibility is -1.
