Question

Which of the following relation is not corect ?
1) B=u0(I+H)
2) B=u0(1+xm)H
3)I=B-u0H×u0
4)xm=u-1 ​

Answer 1

We have to check which one of the following is correct ?

1. $B=\mu_0(I+H)$

2. $B=\mu_0(1+\chi_m)H$

3. $I=B-\mu_0H\times\mu_0$

4. $\chi_m=\mu_r-1$

Solution : option (1) is correct choice. B, I and H are related to one another by, $B=\mu_0(I+H)$ where I is magnetisation, H is magnetic field intensity, B is magnetic field and $\mu_0$ permeability of medium (vacuum).

Option (2) is also correct, magnetic field, magnetic susceptibility are related to one another by, $B=\mu_0(1+\chi_m)H$

Option(3) is incorrect. Relation is $H=\frac{1}{\mu_0}B-I$

Option (4) is correct, $\mu_r=1+\chi_m$

Therefore option (3) is incorrect.
