A) Diamagnetic
B) Paramagnetic
C) Ferromagnetic
D) Ferrite
Correct Answer: A
Solution :
| [a] The magnetic susceptibility of a material is a measure of the ease with which a specimen of that material can be magnetised in a magnetising field. For a diamagnetic substance magnetic susceptibility \[({{\chi }_{m}})\] is independent of temperature. |
| Note: According to Curies law \[{{\chi }_{m}}\] for paramagnetic and ferromagnetic materials varies as\[{{\chi }_{m}}\propto \frac{1}{T},\] T being Kelvin temperature. |
