EXAMPLE 3.10
Compute the intensity of magnetisation of the bar magnet whose mass, magnetic moment and density are 200 g, 2 A m2 and 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.
