Key Idea.
Section 1
Visualizing the Invisible
Since magnetic fields are invisible, scientists use models to study them. The standard model uses magnetic field lines to map the direction and behavior of the force.
These lines provide a visual language: they exit the North pole and enter the South pole. The density of the lines indicates strength—where lines are bunched closely together, the magnetic force is strongest.
Section 2
Patterns of Interaction
The shape of field lines reveals the type of force between two magnets.
