The magnetization is defined by the ratio of(a) Magnetic moment to area(b) Magnetic moment to volume(c) Magnetic flux density to area(d) Magnetic flux density to volumeI had been asked this question during an interview for a job.My enquiry is from Magnetic Dipole topic in chapter Magnetic Forces and Materials of Electromagnetic Theory

Answer»

Correct CHOICE is (B) Magnetic moment to volume

Easiest explanation: The magnetization refers to the AMOUNT of dipole formation in a given volume when it is subjected to a magnetic field. It is given by the RATIO of the magnetic moment to the volume. Thus PM = M/V.
