Question

What is the induced emf if both a magnet and a coil remain stationary?

विकल्प

• An induced emf caused by infinite resistance

• An induced emf caused by constant magnetic flux

• A higher induced emf because flux changes faster

• No induced emf, because there is no change in flux

Answer 1

With the magnet and coil stationary, their relative position does not change. The flux through the coil remains constant, so no emf is induced.
