Question

Electric generator (Dynamo) generates electricity by using the principle ______.

• A. electric circuit
• B. magnetic field
• C. electromagnetic induction
• D. none

Answer 1

The correct option is C electromagnetic induction

Electric generator (Dynamo) generates electricity by using the principle electromagnetic induction

The generator/dynamo is made up of stationary magnets (stator) which create a powerful magnetic field, and a rotating magnet (rotor) which distorts and cuts through the magnetic lines of flux of the stator. When the rotor cuts through lines of magnetic flux it makes electricity.
