Can anyone explain Conservation of energy in Lenz law?
Lenz’s law is based on the conservation of energy. If we take an example of motional emf then if area of loop is decreasing then flux is also decreasing then according to lenz’s law induce current will try to increase it by producing induce current in that direction which will produce its magnetic field in the same direction of source. If it will not so then current direction will suppose to be get reversed and then by applying magnetic force due to induce current( f= BIL) we will get the direction of force in the direction of velocity due to which its velocity will start to increase in that direction due to that force and kinetic energy will increase automatically. Here we didnt provide any source of energy by which it can gain extra energy. So it is not possible, energy cant be created nor be destroyed. So direction of induce current will exist in that direction due to which it willl try to oppose the source flux. Otherwise automatically without any transformation energy will start t
