The following figure shows the variation of intensity of magnetisation $I$ versus the applied magnetic field intensity $H$ , for two magnetic materials $A$ and $B$

Which of the material have a larger susceptibility for a given field at constant temperature?

Question

TestHub · Accepted Answer

Material A is paramagnetic and Material B is ferromagnetic. The susceptibility of material B is larger than A at given magnetic field because ferromagnetic material gets strongly magnetised and hence produces a larger intensity of magnetization in comparison to paramagnetic substance, therefore it is strongly magnetised.
