WebConservation of energy : The fact that electromagnetic induction in accordance with Lenz's law represents the conservation of energy can be easily explained. Consider the figure 5 (a). A repulsive force acts on the bar magnet due to the current induced in the coil. We have to do work in moving the North-pole of the magnet towards the coil.
