Question

Principle behind the working of electric generator?

• A. When a conductor is moved in a magnetic field then voltage is induced in the conductor.
• B. When a conductor is moved in a magnetic field then current is induced in the conductor.
• C. both
• D. none

Answer 1

The correct option is B When a conductor is moved in a magnetic field then current is induced in the conductor.

Principle behind the working of electric generator When a conductor is moved in a magnetic field then current is induced in the conductor.

When a conductor moves in a magnetic field, an emf is induced across the conductor. This is the only basis on which each and every rotating electric generator works. Let us discuss the matter in a little bit details so that we can easily understand how does an electrical generator actually work. According to Faraday's law of electromagnetic induction, when a conductor links with a changing flux, it will have an induced emf across it. The value of induced emf across the conductor depends on the rate of change of flux linkage with the conductor.
