A closely packed coil having $\displaystyle 1000$ turns has an average radius of $\displaystyle 62.8$ cm. If current carried by the wire of the coil is $\displaystyle 1$ A, the value of magnetic field produced at the centre of the coil will be (permeability of free space $\displaystyle =4 \pi \times 10^{-7} \mathrm{H} / \mathrm{m}$) nearly
Official answer
(1)
$\displaystyle 10^{-3} \mathrm{~T}$
