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
