e the soft iron core, and the outer coil, called MAGNETISM. 109 the secondary, is composed of many layers of fine wire, andis insulated from the primary coil. Lines of force from the current transmitted throughthe primary coil, circulating through the secondary coil,induce the transient currents… … Fig. 48. wire, and therefore its resistance, varies also as the num-ber of turns, and the volume of current varies as theresistance, it is evident that as the electric pressure isincreased by increasing the nnmber of turns, the volumeof the induced current is proportionally reduced by the in-crease…
