Question

The magnetic susceptibility is very large in ............... .

• A. Diamagnetic material
• B. Ferromagnetic material
• C. Paramagnetic material
• D. Air

Answer 1

Answer: (B)

Ferromagnetic material

The magnetic susceptibility indicates whether a material is attracted into or repelled out of a magnetic field.

$M=\chi H$ ; where $M$ is magnetization of the material, $H$ is magnetic field strength and $\chi$ is magnetic susceptibility.

Ferromagnetic materials like iron and cobalt, has very large magnetic susceptibility that is positive susceptibility, unlike diamagnetic material which has negative susceptibility.
