A circular conducting coil of radius 1m is being heated by the change of magnetic field 
passing perpendicular to the plane in which the coil is laid. The resistance of the coil is 
. The magnetic field is slowly switched off such that its magnitude changes in time as 
. The energy dissipated by the coil before the magnetic field is switched off completely is E = mJ.
