, `ABCEFGA` is a square conducting frame of side `2 m` and resistance `1 Omega m^(-1)`. A uniform magnetic field `b` is applied perpendicular to the plane and pointing inward. It increases with time at a constant rate of `10 T s^(-1)`. Find the rate at which heat is produced in the circuit, `AB = BC = CD = BH`.
