Answer 1

Answer:

A rectangular frame of wire is placed in a uniform magnetic field directed outwards ,normal to the paper AB which is connected to spring . Explanation : When the spring is stretched and released the wire AB will execute SHM[ simple harmonic motion ]. So induced emf will vary periodically.
