A wire loop PQRSP is constructed by joining two semicircular coils of radii r1 and r2 respectively as shown in the figure. Current is flowing in the loop. The magnetic induction at point O will be-

Two wire loop PQRSP formed by joining two semicircular wires of radii R_(1) and R_(2) carries a current i as shown in the figure given below. What is the magnetic field induction at the centre O in cases (A) and (B) ?

In the loop shown , the magnetic induction at the point 'O' is

In the loop shown , the magnetic induction at the point ‘O’ is

A wire loop is formed by joining two semicircular wires of radii r_1 and r_2 as shown in the figure . The loop carries a current I, find the magnetic field at the centre O.
