Show affiliationsWhen a cylindrical magnet is rotated about its axis, electric fields develop on its surface which can be used to generate continuous currents. This effect is an example of electromagnetic induction, mechanical energy being converted into electrical energy, through the mediation of the magnetic field. It is suggested that the effect can be explained most simply in terms of the forces acting on conduction electrons inside the magnet, rather than in terms of flux linkage and the cutting of lines of force.
