Solution
The correct option is A Electric generator
The change in
magnetic field lines associated with a coil is the cause of
induced electric current in it. This is the principle of Electromagnetic induction. This change can be achieved by:- by moving the coil in a magnetic field or
- by changing the
magnetic field around the coil.
Electric generator uses this principle in which a coil rotates in a magnetic field such that the current is induced in it due to the change in magnetic field lines linked with it.
