13.3: Lenz''s Law. The direction of the induced emf drives current around a wire loop to always oppose the change in magnetic flux that causes the emf. Lenz''s law can also be considered in terms of conservation of energy. If pushing a magnet into a coil causes current, the energy in that current must have come from somewhere.
