Answer:
Step-by-step explanation:
Facts about magnetic flux;
(1). Change in magnetic flux is equal to the current generated.
(2). The magnetic field moves from the north to the south.
(3). Magnetic flux is equal to how much magnetic field goes through a direction.
(4). Magnetlc direction can be found found by using Lenz's law.
Faraday's law= emf= N(BA/ ∆t.
Where N= number of loop
∆B/∆T = rate at which flux changes.
The magnitude φ(initial) of the magnetic flux through one turn of the coil before it is rotated is
φ(initial) = BA while φ(final)= zero(0).
