Section 7.7 The direction of a magnetic field can be seen by placing a compass near a bar magnet. The North pole of the compass points in the direction of the field, away from North and towards South. The magnetic field can also be seen by placing the magnet under a piece of paper and sprinkling small iron filings on top. The filings line up in the shape of the field, as shown at right.

Section 7.7

The North pole of a compass points to the Earth's geographic North Pole, which means that there must be a magnetic South Pole up there.
