Question

Magnetic susceptibility is small and negative for
(1) Diamagnetic substances
(2) Paramagnetic substances
(3) Ferromagnetic substances
(4) All of these​

Answer 1

Answer:

(1) Diamagnetic substances

Magnetic susceptibility is the degree of magnetization of material in response to applied magnetic field.

Thus M=χH

In case of diamagnetic materials, the magnetic field in the material is weakened by the induced magnetization.

Thus, the magnetic susceptibility of diamagnetic materials is negative.

Explanation:

Magnetic susceptibility is the degree of magnetization of material in response to applied magnetic field. In case of diamagnetic materials, the magnetic field in the material is weakened by the induced magnetization. Thus, the magnetic susceptibility of diamagnetic materials is negative.

Answer 2

Answer:

(1) Diamagnetic Substances

Explanation:

Considering Diamagnetic Substances, the magnetic field in the material is weakened by the induced magnetization. Hence, we can say, the magnetic susceptibility of diamagnetic materials is negative.
