It is the degree to which a object is magnetized when placed in a magnetic field.
It can also be described as the pole strength per unit cross sectional area of the object or the induced dipole moment per unit volume.
As I=m/A=M/V. It is a vector value, its S.I. unit is Amp/m.
What type of waves are electromagnetic waves? Feedback: Electromagnetic waves are transverse waves that the oscillations of the electric and magnetic fields are at right
