The object of this paper is to investigate the growth of magnetism in an iron cylinder when the magnetising force is alternating. The shielding effect of induced currents in plates of iron has been dealt with theoretically by Professor J. J. Thomson, and Professor J. A. Ewing. The subject has also been dealt with experimentally in the case of an iron cylinder, 4 inches diameter, with alternating magnetising force and with simple reversal of the magnetising force.
