If the magnetic dipole of moment of an atom of diamagnetic material, paramagnetic material and ferromagnetic material are donated by `mu_d, mu_p` and `mu_f` respectively, then:

Options

A. `mu_(d)=0` and `mu_(p) ne 0`
B. `mu_(d) ne 0` and `mu_(p)=0`
C. `mu_(p) =0` and `mu_(f) ne 0`
D. `mu_(d) ne 0` and `mu_(f)ne 0`

Answer

A

Explanation

The magnetic dipole moment k`mu_(d)` kfo an atom of a diamagnetic matyerial is zero while for paramagnetic and ferromagneitc materials `mu_(p)` and `mu_(f)` are not zero (a) is the correct choice
