Dear student ....The formula used here is the Magnetic field at the centre of circular ring i.e., B=µ0NI/2R.....on solving we get the same answer ....The explanation in the solution is actually the derivation from biot savart law which finally gives B=µ0NI/2R.....With Regards ....Mahima ....(Askiitians Forum Expert )

Magnetic filed due to current current carrying coil on its axis is given by

B = (u₀/4π)(2πnIr²/(x²+ r²)^3/2

here we want to calculate B on centre of circle. SO X =0.

Then B = (u₀/2)(nl/r).

By putting given values in above formula you will get answer.

Hope it clears. If you like anser please approve it.
