1.	Calculate the magnetic field due to a circular coil of `250` turns and of diameter `01m`, carrying a current of `7A` (i) at the center of the coil (ii) at a point on the axis of the coil at a distance `012m` from the center of the coil.
Answer» Correct Answer - (i) `22xx10^-2T` (ii) `125xx10^-3T` (i) `B=(mu_0)/(4pi)(2pinI)/(r)` `=(10^-7xx2xx(22//7)xx250xx7)/((01//2))=22xx10^-2T` (ii) `B=(mu_0)/(4pi)(2pinIa^2)/((a^2+x^2)^(3//2))` `=(10^-7xx2xx(22//7)xx250xx7xx(01//2)^2)/([(01//2)^2+(012)^2]^(3//2))` `=125xx10^-3T`
