Expert Answer
Magnetic induction is the process by which a substance like iron, steel gets magnetized in presence of an external magnetic field.
-
Magnetic intensity ? It is given by the relation,
Where,
B0 ? Magnetic field inside vacuum
?0 ? 4? × 10?7 TmA?1
SI unit ? Am?1
-
Intensity of magnetisation ? It is defined as the magnetic moment developed per unit volume when a magnetic specimen is subjected to magnetising field. It is denoted by I.
I = M/V
SI unit ? Am?1
