What happens to the current in a coil while accelerating a magnet inside it?(a) Increases(b) Decreases(c) Remains constant(d) Reverses

Answer» Correct answer is (a) Increases

For explanation I would say: A change in the magnetic field induces an emf. When there is an emf, there has to be current. Hence, when the magnet is moved inside a coil, the current in it increases.
