Answer» Solution :(a) Magnetic SUSCEPTIBILITY : It is defined as the RATIO of the magnetisation M to the magnetising field intensity H. It is denoted by `X_(m)`. `X_(m)=(M)/(H)` Magnitic susceptibility in terms of magnetic permeability. `X_(m)=mu_(r)-1` (b) A is a diamagnetic material , B is a ferromagnetic material. |
