Study Notes
Magnetism
- The term that describes the concentrated magnetism at the ends of a magnet is poles.
Magnetic Fields
- The number of lines per unit area in a magnetic field represents the magnetic field strength.
Ship's Compass
- The main reason for the superiority of the present-day ship's compass is its ability to accurately indicate direction despite the presence of iron and other interfering objects.
- A ship's compass is typically located near the navigation bridge onboard.
Magnetic Lines of Force
- Magnetic lines of force start at the north pole and end at the south pole of a magnet.
