The only possible Maxwell equation in differential form that describes 
Faraday induction must be:

curl E = -B/t  {partial of B wrt t if symbols don't show}

This seems useless if B does not vary with time.

The references also seem of little value. I might be able to dig up the 
Harvard reference at a local university library. Its title is so 
ungrammatical as to be of no value.

Even though I am an IEEE member, I am not about to spend the money for a 
subscription.

It seems clear to me that special relativity is the easy approach to 
flux "cutting." I just do not see flux cutting arising from the Maxwell 
equation. I am beginning to believe that using the Lorentz force as a 
law by itself is a back road to describe relativity.

Where do we go from here?
