What if we look at gravity from the 'field' point of view, and state that it's magnitude and direction are identical to those of the Lorentz force. What would that mean? (keep in mind that here the lorentz force is secondary. also, what would 'direction' mean to the field of gravity, would it be always to the centre of mass?)
