Which statement about electromagnetic induction is correct?
An electromotive force (e.m.f.) is induced in a conductor only if the conductor is stationary in a static magnetic field.
The magnitude of the induced electromotive force (e.m.f.) is directly proportional to the rate of change of magnetic flux linkage.
According to Lenz's law, the direction of the induced current assists the magnetic flux change that produces it.
The induced electromotive force (e.m.f.) in a coil decreases if the speed of a magnet moving into the coil increases.
