Eddy currents are produced when (a) a metal is kept in varying magnetic field (b) a metal is kept in steady magnetic field (c) a circular coil is placed in a magnetic field (d) through a circular coil, current is passed

Answer: (a). Eddy currents are induced only when the magnetic flux through a conductor changes. A metal piece in a varying magnetic field has changing flux. So the answer is (a).
