Lenz's Law And Faraday's Law Of Induction Beginning of Paper 1. With this definition of the flux being , we can now return to Faraday's investigations. He found that the magnitude of the emf produced depends on the rate at which the magnetic flux changes. Faraday found that if the flux through N loops of wire changes by an amount , during a .... Middle of Paper .... the magnet points upward. To oppose this upward increase, the field produced by the induced current must point downward. Thus Lenz's law tells us that the current must move by the use of the use of the right hand rule. If the flux decreases, so the induced current produces an upward magnetic field that is "trying" to maintain the status quo. Let us consider what would happen if Lenz's law were just the reverse. The induced current would produce a flux in the same direction as the original change; this greater change in flux would pro .... 667 words | 3 pages Subscription Length Price Join 30 days membership (recurring) $19.95 90 days membership (recurring) $39.95 180 days membership (non-recurring) $69.95
