A susceptibility of a certain magnetic material is \( 400 \). What is the class of the magnetic material \( ? \)
- A Diamagnetio
- B Paramagnetio
- C Ferromagnetic
- D Ferroelectrio
Answer & Solution
Correct Answer
(C) Ferromagnetic
Step-by-step Solution
Detailed explanation
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.
