Model Force Fields Practice Test

A bar magnet has a north (N) pole and a south (S) pole. In the magnetic field-line model, lines emerge from N and enter S, curving through the space around the magnet. What does this model tell you about where the magnetic field exists and how it can affect objects?

A bar magnet creates a magnetic field around it. In a field-line model, the magnetic field lines are drawn more densely near the poles and more spread out farther away. What does this model predict about the strength of the magnetic force on a paper clip placed near the magnet?
