EXAMPLE 3.10

Compute the intensity of magnetisation  of the bar magnet whose mass, magnetic  moment and density are 200 g, 2 A mand 8 g cm-3, respectively.

Solution

Density of the magnet is EXAMPLE 3.11 EXAMPLE 3.12

Two materials X and Y are magnetised, whose intensity of magnetisation are 500 A m-1 and 2000 A m-1, respectively. If the magnetising field is 1000 A m-1, then which one among these materials can be easily magnetized?.

Solution

The susceptibility of material X is The susceptibility of material Y is Since, susceptibility of material Y is greater than that of material X, material Y can be easily magnetized than X.
