This is probably a very noob question, but I can't seem to get my head around it. Why does an increase in velocity of a particle in a magnetic field, increase the force acted upon it, according to F_m = QvB? For example in orbital dynamics, an increased velocity of a body simply breaks the orbit, the force does not magically increase, correct? Could anyone guide me in the right direction? What does the F=QvB actually mean?
