Does anyone know if this bit about the Kerr effect is true?  Since the
Kerr effect (pronounced car, I am told) is an electro-optical effect
I don't see where the magnetic field comes into play (except to change
the crystal domain direction).  I keep wondering if someone is confusing
Faraday rotation (which is magnetic field dependent) with Kerr.
Anybody have any references?
