A wire frame of area 4.0 × 10^−4 m^2 and resistance 20 Ω is suspended freely from a 0.40 m long thread. There is a uniform magnetic field of 0.8 T and the plane of wire-frame is made to oscillate under gravity by displacing it through 2×10^−2 m from its initial position along the direction of magnetic field. The plane of the frame is always along the direction of thread and does not rotate about it . What is the induced EMF in wire-frame us a function of time ? Also find the maximum current in the frame.
