Expert Answer:

a) The magnetic flux is maximum when the plane of the coil is perpendicular to the magnetic field i.e, θ = 0°

Therefore, Φ = NBA cos θ = NBA cos 0° =NBA (maximum).

b) The magnetic flux is minimum when the plane of the coil is parallel to the magnetic field i.e θ = 90°

Therefore, Φ = NBA cos θ = NBA cos 90° = 0 (minimum).
