The Force of Magnetism
You may ask, how does the force of Magnetism work?
The force goes
from one pole to another. A pole can be described as the point where the force is pointed.
Most magnets have two poles, as shown in this picture. Planets can have more than two poles. The magnetic field "lines" illustrate where the force of magnetism is, and whether it is stronger (red) or weaker (blue).
