Sol 4.1

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 the magnetic field at the centre of the coil is given by the relation,

| B | = μ0 2πnI / 4π r

Where,

μ0 = Permeability of free space

= 4π × 10–7 T m A–1

| B | = 4π x 10-7 x 2π x 100 x 0.4 / 4π x 0.08

       = 3.14 x 10-4 T

Hence, the magnitude of the magnetic field is 3.14 × 10–4 T.

Sol 4.2

Current in the wire, I = 35 A

Distance of a point from the wire, r = 20 cm = 0.2 m

Magnitude of the magnetic field at this point is given as:

B  attached above

Where,

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

attached above

Hence, the magnitude of the magnetic field at a point 20 cm from the wire is 3.5 × 10–5 T.
