Are the directions of charge flow (=current?) absolute?

Sure, if you want to call the change of momentum of the field a force then you could certainly say that. It is not common, but I have no problem with it. It seems that you now understand the point I have been making since post 43.

It's not common? Really?

EM fields are regarded as mediators of momentum, but you say they are usually not regarded carriers of force. Contrarily, what I read about EM implies that the EM field consists of force. In fact, EM is one of the "fundamental forces" known to physics.

The definition of force is quite clear from Newton's formulation. If a system has momentum being exchanged, then there is force.

Really, really.
