Abstract

This paper presents a simple new rule that is followed by every free charged particle in acceleration caused by a spatially-uniform magnetic field. Every particle in such magnetic acceleration has, not only an acceleration with respect to a stationary reference frame, but also an acceleration with respect to a rotating reference frame, which rotates about the direction of the magnetic field with a quasi Larmor frequency; these two accelerations are in constant ratio. This simple new rule is followed perfectly, regardless of how the other concerned laws of physics operate. This simple new rule brings us a brand new picture of magnetic acceleration, and a brand new analytic tool as well.
