Two magnetic materials A and B have relative magnetic permeabilities of 0.96
and 500. Identify the magnetic materials A and B.

'A' is diamagnetic material as its permebility lie b/w 0 to 1. Its susceptibility is negative. 'B' is paramagnetic material as its permeability is greater than 1 or unity . Its susceptibility is positive .
