 2805  242 Electromagnetic Induction Report Error

Solution:

The laws of electromagnetic induction have been used in the construction of an electric generator.
In an electric generator, emf is induced by changing the flux.
A galvanometer is used to detect current. So, no use of electromagnetic induction.
The voltmeter is used to measure voltage.
Again, no use of electromagnetic induction.
Electric motor changes electrical energy into mechanical energy, which has no use of laws of electromagnetic induction.
