What is Lenz's Law?-Definition with Diagram Electrical Concepts . Lenz's Law states that the direction of the induced current is such that it opposes the change that has induced it. In other words, lenz's law is defined as Effect Opposes the Cause. It is used to find the direction of induced current in a conducting loop. Lenz's Law of Electromagnetic Induction Electrical4U . Lenz's law is named after the German scientist H. F. E. Lenz in 1834.Lenz's law obeys Newton's third law of motion (i.e to every action there is always an equal and opposite reaction) and the conservation of energy (i.e energy may neither be created nor destroyed and therefore the sum of all the energies in the system is a constant).
