In the figure shown ABCDEFGH is a square conducting frame of side 2m and resistance  1Ω /m  A uniform magnetic field B is applied perpendicular to the plane and pointing inwards. It increases with time at a constant rate of  10 T/ s . Find the rate at which heat in watt is produced in the circuit  $\mathrm{AB}=\mathrm{BC}=\mathrm{CD}=\mathrm{BH}$
