A circular conducting coil of radius 1 m is being heated by the change of magnetic field `vec(B)` passing perpendicular to the plane in which the coil is laid.
The resistance of the coil is `2mu Omega` The magnetic field is slowly switched off such that its magnitude changes in time as
`B=(4)/(pi)xx10^(-3)T(1-(t)/(100))`
The energy dissipated by the coil before the magnetic field is switched off completely is E = ____________ mJ.
