Question

Find the magnetization of the field which has a magnetic moment 16 units in a volume of 1.2 units.

(a) 16.67

(b) 13.33

(c) 15.56

(d) 18.87

I have been asked this question during a job interview.

This intriguing question comes from Magnetic Dipole in portion Magnetic Forces and Materials of Electromagnetic Theory

Answer 1

The correct option is (b) 13.33

The explanation: The magnetization is the ratio of the magnetic moment to the volume. Thus M = m/v, where m = 16 and v = 1.2. We get M = 16/1.2 = 13.33 units.
