The rotational system that forms the basis of particles and atoms has two, magnetic (2D) rotations and a single electric (1D) rotation.

A magnetic rotation can be visualized as a disk with a radial measure. Larson's two, magnetic rotations form two, interpenetrating disks to produce the two, magnetic rotations that are designated "a" and "b" in the a-b-c notation. Technically, the "a" rotation is a x a and the "b" rotation is a x b, as the second, or

*subordinate*rotation shares a common axis with the primary rotation. "a" therefore has the dimensions of a

^{2}and "b" is "ab". Larson only uses the "a" and "b" values to represent magnetic rotations.

The electric rotation is a spinning of the magnetic rotating system, in a single dimension, like spinning a ball.

The system can be visualized like this (the rotating system of a particle; atoms have

*two*of these rotating systems, of the same displacements):
