If current 'I' is flowing in the closed circuit with collective resistance 'R', the rate of production of heat energy in the loop as we pull it along with a constant speed 'V' is (L = length of conductor, B = magnetic field)
1
\(\frac{\text { BLV }}{\mathrm{R}}\)
2
\(\frac{B^2 L^2 V^2}{R^2}\)
3
\(\frac{B L V}{R^2}\)
4
\(\frac{B^2 L^2 V^2}{R}\)
