अनुचुम्बकीय पदार्थ के प्रत्येक परमाणु का स्थायी चुम्बकीय आघूर्ण होता है

Options

A. must be ferromagnetic
B. must be paramagnetic
C. must be diamagnetic
D. may be paramagnetic

Answer

D

Explanation

Ferromagnetic materials have large magnetic moment but paramagnetic have small magnetic moment. But in this question nothing is said about the magnitude of magnetic moment. It is certainly not diamagnetic material. We cannot say it must be ferromagnetic because magnetic moment may be small and similarly we cannot say that it must be paramagnetic because magnetic moment may be large.
