In the circuit shown in figure. The ring is made of a wire of uniform $$cross-sectional$$ area. If magnetic induction at the centre O produced by the segment ACB is $$25$$µT, what will be the magnetic induction at O produced by the segment ADB ?

Question

Infinity Learn · Accepted Answer

Resultant magnetic induction at O is zero.Since the lengths of ACB and ADB are in the ratio of $$5$$:$$1$$. The currents will divide in the ratio $$1$$:$$5$$. As a result the magnetic induction produced by the two arcs will be equal and opposite in direction cancelling each other.Thus magnetic induction at center is equal to zero∴magnetic induction produced by ADB $$=$$ magnetic induction produced by $$ACB=$$ $$25$$ µT (outward)
