    Among the choices, electromagnetic induction produces an electric current.

    WHY:

    Electromagnetic Induction produces an electric current when an electromotive force or voltage moves across an electrical conductor in a changing magnetic field. As an experiment, moving a bar magnet inside a coil will produce emf (electromotive force) or voltage thereby producing a current.
