1.	L is a circular ring made of a uniform wire. Current enters and leaves the ring through straight conductors which, if produced, would have passed through the centre C of the ring. The magnetic field at C (a) due to the straight conductors is zero (b) due to the loop is zero (c) due to the loop is proportional to θ(d) due to the loop is proportional to (π - θ)
Answer» Correct Answer is: (a) due to the straight conductors is zero, (b) due to the loop is zero
