The same current is passed through two identical conducting wires of the same length L. One of them, $\displaystyle \mathrm{w}_1$, is bent in the form of a circular loop of $\displaystyle \mathrm{N}_1$ turns while the other wire, $\displaystyle \mathrm{w}_2$, is bent in the form of a circular loop of $\displaystyle \mathrm{N}_2$ turns. The ratio of the magnetic fields at the centre of the coils $\displaystyle \mathrm{w}_1$ and $\displaystyle \mathrm{w}_2$ will be -
