This interactive resource from the physics department at Boston University illustrates Coulomb's law. The simulation allows the user to graph the dependence of the Coulomb force on the distance between charges.

The effect of the commutator is to produce a fixed spatial distribution of current directions in the armature conductors (shown as blue & green circles) independent of shaft rotation. The field created by these currents...
