Answer:

Number of turns on the circular coil, n = 100

Radius of each turn, r = 8.0 cm = 0.08 m

Current flowing in the coil, I = 0.4 A

Magnitude of magnetic field at the centre of circular coil is given as:

B = (μ0/ 4π) ((2 π n l) /r)

Where μ0 = Permeability of free space = 4π × 10–7 T m A–1

Therefore B = (4π × 10–7 x 100 x 0.40)/ (2 x 8 x10-2)

B = 3.14 x 10-4 T
