An induced emf arises from a change in magnetic flux. This change can be caused by the motion of a conductor in a magnetic field (changing the area perpendicular to the field) or by a change in the magnetic field itself through a fixed area.
Consider the following statements: (i) An emf can be induced by moving a conductor in a magnetic field. (ii) An emf can be induced by changing the magnetic field.
