What happens to the current in a coil while accelerating a magnet inside it?(a) Increases(b) Decreases(c) Remains constant(d) ReversesThis question was addressed to me in final exam.The question is from Electromagnetic Induction in portion Electromagnetism of Basic Electrical Engineering

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.
