A wire frame of area `3.92xx10^(-4)m^(2)` and resistance `20Omega` is suspended freely from a 0.392m long thread. There is a uniform magnetic field of 0.784 T and the plane of wire-frame is made to oscillate under gravity by displacing it through `2xx10^(-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.
