WebbThe induced emf produces a current that opposes the change in flux, because a change in flux means a change in energy. Energy can enter or leave, but not instantaneously. Lenz’s law is a consequence. As the change begins, the law says induction opposes and, thus, slows the change. great-sand-dunes-nationalparkWebbThe EMF or electromotive force is the energy supplied by a battery or a cell per coulomb (Q) of charge passing through it.
