Let's take a look at Faraday Lenz Law.
I had that the EMF is equal to the
negative change in the magnetic flux
over the change in time. This is the
voltage. Well, if you think about the
relationship between voltage and the
electric field is that the electric
field is equal to the change in voltage -
negative change in voltage over the
change in position, so E Delta x is just
equal to Delta V. I'm ignoring the signs
right now, doing it just hand wave
around it. And so this EMF can also be
expressed as the sum of the electric
field times Delta l, x whatever what are
you happen to using around a closed loop,
it's equal negative Delta Phi sub m over
Delta t, and so this is another way of
expressing Faraday Lenz's Law.
