Question 75: Magnetism and Matter

Question

Two insulated circular loop A and B of radius '$a$' carrying a current of '$\mathrm{I}$' in the anti clockwise direction as shown in the figure. The magnitude of the magnetic induction at the centre will be :

Accepted Answer

$\because B_{n e t}=\frac{\sqrt{2} \mu_0 I}{2 a}$

Answer

$\frac{\sqrt{2} \mu_0 I}{a}$

Answer

$\frac{\mu_0 I}{\sqrt{2} a}$

Answer

$\frac{\mu_0 \mathrm{I}}{2 \mathrm{a}}$

Answer

$\frac{2 \mu_0 I}{a}$
