The frequency with which a magnet plunges into and out of a wire coil equals the frequency of the induced

Question

Quizplus · Accepted Answer

The frequency of the induced voltage and current in a wire coil directly corresponds to the frequency at which a magnet plunges into and out of the coil. This is because the changing magnetic field, as the magnet moves in and out, induces an electromotive force (EMF) and consequently a current in the coil, both of which will oscillate at the same frequency as the magnet's motion.
