Question

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?, Material B, Material B and Material A have the same susceptibility, Material A, None of these

MARKS App · 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.
