ce the magnetism will increase 1056 Steam Engineering and more voltage will be induced. This voltage will sendincreased current through the shunt field, and cause morevolts to be induced. The machine is now ^^building up.^^ As more and more magnetism is put into the fields, itbecomes harder to get… … Fig. 449 added to the effect of the leakage just balances the tendencyof the voltage to be increased. If nothing else is done thevoltage of the dynamo will remain constant. In the series field, is passing all the current drawn fromthe machine, and the field strength and voltage tend to in-crease.…
