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.
Show the types of chromatic aberration. What do you understand by Fraunhoffer lines? Explain their origin.
It is the property of the substance which defines how easily a substance can be magnetized. It may also be defined as the ratio of intensity of magnetization (I) in a substance to
