Super conductig square rigid frame of mass m, self inductance L and side a is cooled down (in a magnetic fiel d) to a temperature below the critical temperature. The frame is kept horizontal (parallel to the x-y plan e) and constarined to move in the z- direction in a non - uniform but constant magnetic field given by →B=−αx^i+(αz+B0)^k and a uniform gravitational field given by accelaration −g^k as shown in figure. The thickness of the frame is much smaller than a. Initially the frame is at rest with its centre conciding with the origin. Now the frame is released at t=0.Maximum magnitude of Z - cordinate of centre of loop during subsquent motion will be?
