Line Integrals on a closed Loop: Faraday's Law

^_^_^_^_^_^_^_^_^_^   Faraday's Law:   ^_^_^_^_^_^_^_^_^_^












Imagine a line integral of the dot product of E and ds in a closed loop, and you have Faraday's Law for integrating the Electric Field to obtain the Magnetic Flux. This is equal to the generated voltage in that loop.
Faraday's Law summarizes the ways voltage can be generated. This graphic to the right helps me remember just whats going on (the line integral takes place over a scalar or vector field and is a closed loop)
