That is not the case, so this is a new discovery - the Lorentz force does NOT have an equal and opposite reaction.
Your point is merely theoretical.
My evidence is experimental.

I urge you to repeat my experiments honestly and competently instead of persisting with theory proved wrong.

Blah blah. Theoretical stuff. One may as well say the sun goes around the Earth because holy books and great people and Aristotle say so.

Diversion, how unscientific. 

Disgusted.
