A generator producing a varying current from 0 to 10 A was allowed to flow in a coil of magnetic field. After a time interval the current was observed to be 4 A. Describe how back EMF was enduced in self induction​

Answer:

the emf generated by a magnetic coil of the generator, because it consists of a coil turning in a magnetic field; it opposes the voltage powering the motor, so at first the current reaches 10A but subsequently due to the back emf generated in the coil this emf opposes the self induced emf thereby reducing the current to 4A
