Question

The value of the intensity of magnetization of the magnetic material when magnetising field is reduced to zero

Answer 1

Given that,

When magnetising field is reduced to zero.

We know that,

Magnetic induction :

The magnetic induction is directly proportional to the addition of the magnetic field and intensity of magnetisation.

In mathematically,

$B\propto \mu_{0}(H+I)$

$B=\mu_{0}(H+I)$

Where, B = magnetic induction

H = magnetic field

I = intensity of magnetisation

If the magnetising field is reduced to zero

$H=0$

We need to calculate the value of the intensity of magnetization of the magnetic material

Using formula of magnetic induction

$B=\mu_{0}(H+I)$

Put the value into the formula

$B=\mu_{0}(0+I)$

$B=\mu_{0}I$

$I=\dfrac{B}{\mu_{0}}$

Hence, The value of intensity of magnetization of the magnetic material is $\dfrac{B}{\mu_{0}}$
