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

A

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

B

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

C

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

D

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