Physics Vocabulary

3. A naturally magnetized mineral (magnetite) that has been used as a compass since ancient times.
4. Microscopic regions in a ferromagnetic material where the magnetic fields of the atoms are aligned in the same direction, creating a net magnetic field for the entire domain.
6. The magnetic pole of a magnet that points towards the geographic north pole.
7. The magnetic pole of a magnet that points towards the geographic south pole.
9. The two points (North and South) on a magnet where the magnetic field is the strongest and most concentrated.
11. A magnet that retains its magnetic properties even in the absence of an external magnetic field.
12. A stream of charged particles (mostly protons and electrons) ejected from the Sun that can interact with the magnetic field of a planet.
13. A material that is not attracted to a magnet and does not have magnetic properties.

1. A region of space surrounding a magnet, where the magnetic force is exerted on other magnets or magnetic materials.
2. The region around a planet where its magnetic field is dominant and protects the planet from the charged particles of the solar wind.
5. A type of material that is strongly attracted by a magnetic field and can retain its magnetic properties even after the field is removed (e.g. iron, nickel, and cobalt).
8. A pair of equal and opposite electric charges or magnetic poles separated by a distance.
10. A magnet that exhibits magnetic properties only when it is placed in an external magnetic field.
