A circular coil having an area of \(3.14 ×10^{-2} m^2 \)and 30 turns is rotated about its vertical diameter with an angular speed of \(70 \;rad^{-1}\)in a uniform horizontal magnetic field of magnitude \(5×10^{-1} T. \) If the coil forms a closed loop of resistance 15Ω, what is the average power loss due to joule heating?
