A susceptibility of a certain magnetic material is ( 400 ). What is the class of the magnetic material ( ? )

Options

  1. ADiamagnetio
  2. BParamagnetio
  3. CFerromagnetic
  4. DFerroelectrio

Correct answer

C. Ferromagnetic

Step-by-step solution

Magnetic susceptibility is a dimensionless quantity. It indicates degree of magnetisation of material in response to an applied magnetic field. For the given magnetic material susceptibility is ( 400 ). Since the susceptibility is positive and possess permanent magnetisation, therefore, material is ferromagnetic.
