Detailed Solution

The above statement is True.
Faraday's first law of electromagnetic induction states, "When a conductor is placed in a varying magnetic field, an electromotive force is induced.
In the same way, if the conductor circuit is closed, a current is induced, known as induced current."
The transformer works on Faraday's electromagnetic and mutual induction law. There are generally two coils, one is the primary coil, and the other is the secondary coil on the transformer core. The core laminations are attached in the form of strips. Also, the two coils have high mutual inductance. Hence proving that the transformer works based on Faraday's law.
