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

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