An electric generator works on the principle of electromagnetic induction.
The given statement is true i.e electric generator works on the principle of electromagnetic induction.
Electromagnetic induction is the phenomenon in which an emf is induced in the coil if there is any change in the magnetic flux linked to the coil. In a generator, a coil is rotated in a magnetic field, due to which magnetic flux linked with the coil changes and induces an emf.
