`L` is a circular ring made of a uniform wire, currents enters and leaves the ring through straight conductors which, if produces, would have passed through the centre `C` of ring. The magnetic field at `C` (i) due to the straight conductors is zero (ii) due to the loop is zero (iii) due to the loop is proportional to `theta` (iv) due to loop is proportional to `(pi-theta)`A. due to the straight conductors is zeroB. due to the loop is zeroC. due to the loop is proportiona to `theta`D. due to the loop is proportional to `(pi-theta)` |
