A circular conducting coil of radius 1 m 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 2 . 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.
