Question

An iron rod of cross section 1 cm is placed in
magnetic field of 200 orested. It proudces a
magnetic field of 3000 G. Find magnetic
permeability and magnetic suceptibility of the
material.​

Answer 1

Answer:

Given : Cross-sectional area A=1cm

2

Magnetising field H=200 oersted

Produced magnetic field B=3000G
