Magnetic susceptibility for a paramagnetic and diamagnetic materials is respectively,A. small, positive and small, positiveB. large, positive and small, negativeC. small, positive and small, negativeD. large, negative and large, positive

Answer» Correct Answer - C
The magnetic susceptibility of a magnetic substance is defined as the ratio of intensity of magnetisation (l) to magnetic intensity (H), i.e.
`x=(l)/(H)`
For paramagnetic material, x is positive and small `(0ltxltepsilon)`, where is smaal positive number.
For diamagnetic meterial, x is negative and small `(-1lexle0)`.
