Book N Chapter 1 Study Guide
1. Magnet: Material with atomic domains that line up to form North and South poles. By lining up this
way, magnets form a magnetic field that interacts with nature, some metals, and other magnetic
materials.
2. Magnetic Force: The force around a magnet that attracts or repels.
3. Magnetic Field: The energy field that surrounds a magnet. This field is LIMITED based on the size and
strength of the magnet.
4. Magnetic Field Lines: Invisible lines that map out where a magnetic field is. Normally they connect
North and South poles by curving around the magnetic object.
5. Magnetic Poles: The two ends of a magnet where the magnetic force is the strongest. All magnets
have poles that are marked "north/south" or +/-.
6. Magnetic Domain: A group of atoms in a magnet that have electrons spinning in the same direction.
7. Ferromagnetic material: Any material that shows strong magnetic properties.
8. Temporary Magnet: A metal substance that temporarily becomes magnetic whenever it comes in
contact with a permanent magnet.
9. Permanent magnet: A magnet that remains magnetic forever unless it is either melted or split apart.
10. Compass: An instrument used for navigation with a magnetized needle that always points north.
11. Magnetic Declination: The angle between magnetic North and geographic North. This can change
over time.
12. Van Allen Belts: Areas in space near the earth that are filled with charged protons and electrons
traveling at high speeds.
13. Solar Wind: A stream of electrically charged particles flowing at high speeds from the sun.
14. Magnetosphere: The magnetic field of the earth.
15. Aurora: A weather phenomenon caused by the solar wind and gas molecules/plasma in the upper
atmosphere. Auroras are caused by a combination of solar wind storms and the earth's magnetic field.
Energized gas molecules and plasma emit light that we see as the Northern Lights, or Aurora Borealis.
Other Magnet Facts:
1. Magnetism is a part of the triune nature of light God spoke on Day 1 of Creation.
2. Magnetism and electricity are inter-connected in that each produce energy that we utilize.
3. Magnetism is caused by the spinning of electrons in atoms that are arranged in domains (atoms that
spin in the same direction). Domain patterns in magnets cause north and south poles, and the shape of
the magnetic field.
4. Geologic history in rocks show that at one time, the earth's magnetic field was reversed to where
compass needles would have pointed south instead of north. Scientists know this by reading the
alignment patterns in volcanic rock that erupted on the ocean floor thousands of years ago and then
cooled.
5. If you break a bar magnet in half, then you will have two separate magnets that each have a north
and south pole. Only when a magnet is completely disorganized through melting or crumbing (grinding)
will it lose its magnetism.
6. It is believed that convection currents in the earth's core produce the earth's magnetism.
