Expert Answer:

begin mathsize 11px style straight ϕ equals straight B with rightwards arrow on top times straight A with rightwards arrow on top end style =BA cos θ


B is the strength of the magnetic field.

A is the area of the surface

θ is the angle with normal to the surface area makes with the direction of   magnetic field.

If a coil has N turns, then begin mathsize 12px style straight ϕ equals NBA space cosθ end style
