A long conducting wire having a current $I$ flowing through it, is bent into a circular coil of $N$ turns.Then it is bent into a circular coil of $n$ tums. The magnetic field is calculated at the centre of coils in both the cases. The ratio of the magnetic field in first case to that of second case is:
