he load is thrown off. As far as the author is awarethe system has not been tried in actual practice, andthere are theoretical reasons for expecting that it wouldnot work. From equation 7) it will be evident that thefield must be strongest when the load is greatest. Nowsuppose that the differential… … effect will be to slightly reduce the speed, and in conse-quence of the reduction in speed the magnetizing currentin the fine wire coil will also be reduced. The field willthus be slightly weakened. This will further reduce thespeed and again weaken the field, and so on, until thearmature comes to…
