Under the hypothesis that ordinary matter is ultimately made of subelementary constitutive primary charged entities or partons'' bound in the manner of traditional elementary Planck oscillators (a time-honored classical technique),
it is shown that a heretofore uninvestigated Lorentz force (specifically, the magnetic component of the Lorentz force) arises in any accelerated reference frame from the interaction of the partons with the vacuum electromagnetic zero-point field (ZPF).
Partons, though asymptotically free at the highest frequencies, are endowed with a sufficiently large bare mass'' to allow interactions with the ZPF at very high frequencies up to the Planck frequencies
