When a magnet is moved into a coil of 50 turns at 0.12m/s an emf of 3.6V is generated in the coil.What will be the emf generated when the magnet is removed from the coil at 0.48 m/s
N (number of turns) is known as the constant of proportionality - doesn't change.
Sooooo... to get from 0.12m/s to 0.48m/s you have to multiply by 4. Hence your answer is 3.6(4)
