So im stuck on this question and how to actually do it

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

According to Faraday's law of electromagnetic induction, magnitude of induced emf is directly proportional to the rate of change of magnetic flux linked with the circuit. So, emf is directly proportional to the speed of the magnet traveling through the coil.
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)
