completeness of the Maxwell equations #64

Closed ericmazur closed 9 years ago

From @JohnDenker: This one is obviously a typo. I know you know this stuff.

Referring to the Maxwell equations, on page 800 it says: "Together with conservation of charge, these four equations give a complete description of electromagnetic phenomena."

The first clause is wrong coming and going. Surely you meant to say "Together with the Lorentz force law, ...."

a) Conservation of charge is a corollary of the Maxwell equations. Proving this is trivial -- but interesting.

b) The Lorentz force law is necessary, but it is not a corollary of the Maxwell equations.
