Chapter 18: Faraday's Law and Lenz's Law

Definition of Magnetic Flux

If the magnetic field is uniform in space (at any particular time), the equation for flux simplifies to

Weber

SI unit for flux

Flux Through a Coil

Faraday’s law (scalar form)

Faraday’s law, form II

Lenz’s law

The induced current produces a magnetic field, which in turn produces a flux that opposes the change in flux in the loop caused by the changing external magnetic field.
