Nothing matters a lot

An electromagnetic field can exert a force on a charged particle. The expression for this force, viz. the Lorentz force, is given by q(E +v×B). This tells you that, if E and B vanish, then there is no force. Similarly, we do not expect any Lorentz force to arise when there are no charged particles. All these sound quite reasonable.
