esecondary coil. The action of the transformer is as follows. When the al-ternating current from the dynamo passes through the wireof the coil P in one direction, it makes the ring a magnet.This magnetism passes through the secondary coil 5 and pro-duces an induced current. The next instant the… … INDUCED CURRENTS 231 dynamo reverses its direction 50 times a second, the inducedcurrent produced in S also reverses 50 times a second. The important feature of the transformer is that it takes analternating current of one voltage and produces a new alter-nating current of a higher or lower voltage…
