Solving time: 3 mins

In the figure shown $A BC$ is a circle of radius $a$ . Arc $A B$ and $A C$ each have resistance $R$ . $A rc BC$ has resistance $2 R$ . A current $I$ enters at point $A$ and leaves the circle at $B$ and $C$ . All straight wires are radial. Calculate the magnetic field at the centre of the circle. Each arc $A B, BC$ and $A C$ subtends $12 0^{\circ}$ at the centre of the circle.

will have equal potential and there will be no current in arc

BC

. Current

I

gets divided into two equal parts at

A

∴ B_{A B} ∴ B_{centre} = \frac{μ _{0} ( I /2 )}{2 a} \otimes B_{A C} = \frac{μ _{0} ( I /2 )}{2 a} ⊙ = 0
