A $\displaystyle 100$-turn closely wound circular coil of radius $\displaystyle 5$ cm has a magnetic field of $\displaystyle 3.14 \times 10^{-3} \mathrm{~T}$ at its centre. The current flowing through the coil, and the magnitude of the magnetic moment of this coil are, respectively : (Take $\displaystyle \mu_0=4 \pi \times 10^{-7} \mathrm{~T} \mathrm{~m} / \mathrm{A}$ )
