Faraday's law using graphs

 

Magnetic flux is
To visualize the flux, consider a metal rings that conducts electricity.
Faraday's law says an emf is generted when the flux is changed.
This can be modeled on a graph of Flux vs. time.
On this graph the slope if the change in flux.
What conclusions can be drawn from the graph? Apply Ohm's law to the emf in Faraday's law.
Therefore,
