Induced emf in coils, Electrical Engineering

Assignment Help:

Faraday conducted a series of experiments on coils in a magnetic field.

He found that if the magnetic flux density threading a coil were changed, a voltage was induced in the coil and a current flowed if the circuit was closed.

This was true however the change in flux is produced  e,g,

1) relative movement between the coil and the magnetic field

2) a change the current flowing in a nearby coil 

3) a change in the current flowing in the coil itself.
