    An electric motor runs on which principle ?

    a) The current flowing through a conductor causes generation of heat that drives the engine.

    b) Changing magnetic field induces an electromotive force in a conductor.

    c) Electric energy can be converted into chemical energy in the presence of magnetic fields.

    d) A conductor carrying current in the direction perpendicular to the external magnetic field feels a force.
