A battery is connected between two points A and B the circumference of a uniform conducting ring of radius r and resistance R One o the arcs AB of the ring subtends an angle at the centre The value of the magnetic induction at the centre due to the current in the ring is a zero only if 0 180 c proportional to 2 180 0 b zero for all values of e d inversely proportional to r 4 B
