A rectangular loop which was initially inside the region of uniform and time - independent magnetic field, is pulled out with constant velocity v as shown in the figure

a) Sketch the variation of magnetic flux, the induced current, and power dissipated as Joule heat as function of time.
b) If instead of rectangular loop, circular loop is pulled out, do you expect the same value of induced current? Justify your answer. Sketch the variation of flux in this case with time.
