Question

Define magnetization. State its formula, SI unit and dimension. What is the magnetic susceptibility of a medium?​

Answer 1

Explanation:

Any device which has magnetic north pole and south pole on opposite sides is known as a magnetic dipole. It can be a bar magnet, a bar electromagnet, a current carrying ring or a solenoid etc.

The strength of a pole of a dipole is called pole strength. Its SI unit is ampere.metre A.m, and denoted by m.

In any dipole the pole strength of both the poles are always equal. The product of the strength of one of the poles and the distance between the poles is known as magnetic dipole moment. It is denoted by M and its SI unit is ampere.metre

Answer 2

Definition:-

The magnetization of a material may be defined as the net magnetic moment per unit volume of the material.

Formula :

Magnetization = Net mangnetic moment / volume

SI unit : =A/m. (Ampere per meter)

Dimension :- [ M° L^-1 T° I^1 ]

Magnetic susceptibility of a medium:-

Magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field. It is caused by interactions of electrons and nuclei with the externally applied magnetic field.
