Chpts. 31, 32 Electromagnetic Induction
Faradays Law of Induction the emf induced in a
circuit equals the rate of change of the magnetic
flux through the circuit. Niagara Falls

Motional emf
5
Lenzs Law
Lenzs law states that the direction of the
induced emf is such that it produces a current
that creates a magnetic flux that opposes the
original change in magnetic flux.
