Find the magnetization of a bar magnet of length 5 cm and cross-
sectional area 2cm?, if the magnetic moment is 1 Am..
inahan​

Answer 1

Mnet= 1 Am

I= 5cm= 5*10−2m

AREA of cross section= 2 cm2 = 2*10-4m2

magnetization= v= 5*10-2*2*10-4

v= 10*10-5m3

magnitisation= 1/10-5

=10 raise to power 5 A/M
