What is Faraday's Law?
When the flux linking an electrical circuit is changing, an emf is induced in the circuit of magnitude equal to the rate of change of flux linkage.
When the flux in an electrical circuit is changing, an emf is induced in the circuit of magnitude equal to the rate of change of flux.
The direction of any current resulting from an induced emf is such as to oppose the change in flux linkage that is causing the current.
The direction of any current resulting from an induced emf is such as to oppose the change in flux that is causing the current.
