One of the two identical conducting wires of length L is bent in the form of a circular loop and the other one into a circular coil of N identical turns. If the same current passed in both, the ratio of the magnetic field at the central of the loop `(B_(L))` to that at the central of the coil `(B_(C))`, i.e. `(B_(L))/(B_(C))` will be :
