Q1:

In a homogeneous magnetic field H of a solenoid, the core carries a magnetic dipole moment M per unit volume equal to

A μ0 H

B μr H

Cr - 1) H

D μoμr H

ANS:C - (μr - 1) H

The magnetic moment is the magnetic strength and orientation of a magnet or other object that produces a magnetic field.
