Dear studentGiven,Radius of circular coil, r=0
2 mNumber of turns, n=100Current, I=1
2 Aa Magnetic field at the centre of the coil B is given byB=μ04π2πnIr⇒B=4π×10-7×100×1
22×0 2⇒B=3
765×10-4 Tb Magnetic field on the axis of the coil is given byB=μ04π2πnIr2r2+x232⇒B=4π×10-74π2π×100×1
2×0 220 12+2232⇒B=2×3
14×10-7×100×1 2×0 040 01+432⇒B=30
144×10-7432       ∵ 4
01≈4⇒B=30 144×10-78=3
