The transformeris a very efKcient pieceof mechanism ; in thelarge t3pes but two and sometimes as little as one per centof the energy transformed being lost. This is divided up between the C R loss or the energylost in heat in the circuit and the heating, resulting from themagnetic reversals in the iron. The magnetic loss is due to the cross Hux between theprimary and secondary, surrounding one coil oidy, withoutbeing interlinked with the other. This is but a small por-. WliSllNOHOUSE TKANSFlCOILS.
