MAGNETIC MATERIALS

Assertion: Poles of a magnet can never be separated. Reason: Since each atom of a magnetic material is a magnet in itself.

Assertion: Above Curie temperature, a frerromagnetic material becomes paramagnetic. Reason: When a magnetic material is heated to very high temperature, it loses its magnetic properties.

Hardness of a magnetic material is measured by the value of , Magnetic induction, Intensity of magnetisation, Density of magnetic material, or Coercive force?

The relative magnetic permeability of a magnetic material is 800. Identify the nature of magnetic material and state its two properties.

The susceptibility of a magnetic material is -2.6xx10^(-5) . Identify the type of magnetic material and state its two properties.
