Study Notes
Magnetic Properties
- A magnet's property that allows it to attract certain materials is magnetism, which is a force that arises from the interaction of magnetic fields.
Magnet Fragmentation
- When a magnet is broken into two pieces, each piece becomes a new magnet with its own north and south poles.
Earth's Magnetic Field
- The Earth's magnetic field is primarily responsible for guiding migratory birds and other animals during their navigation.
- The Earth's magnetic field also protects the planet from harmful solar winds and charged particles from space.
