WebThe ends of a magnet are called its poles. One end is called the north pole, the other is called the south pole. If you line up two magnets so that the south pole of one faces the … WebThus the rate of change of the magnetic flux is. Δ Φ Δ t = Δ ( B A cos θ) Δ t = B Δ A Δ t = B v ℓ, 20.34. where we have used the fact that the angle θ between the area vector and the magnetic field is 0°. Once we know the emf, we can find the current by using Ohm’s law.
