Question
The magnetic susceptibility is negative for _____________ .
Options
paramagnetic materials only
diamagnetic materials only
ferromagnetic materials only
paramagnetic and ferromagnetic materials
Solution
diamagnetic materials only
Magnetic susceptibility is defined as the ratio of the intensity of magnetisation induced in the material to magnetising foorce applied on it.
Magnetic susceptibility is negative for diamagnetic materials. Magnetic susceptibility is positive for paramagnetic and ferromagnetic materials.
