We know that the angle θ between the area of the coil and the direction of the magnetic field is 90∘ when the coil is parallel to the field.
The formula for magnetic flux is φ=NBA‌cos‌θ, where N is the number of turns, B is the magnetic field, A is the area, and θ is the angle.
Substitute θ=90∘ into the formula. We get:
φ=NBA‌cos‌90∘=0
This is because cos‌90∘=0.
