Explain the difference between a temporary magnet and a permanent magnet.
Explain the difference between a temporary magnet and a permanent magnet.
A temporary magnet can be magnetized for a short period by rubbing it with a permanent magnet, while a permanent magnet retains its magnetism without external influence.
How does the Earth act like a giant magnet?
How does the Earth act like a giant magnet?
The Earth's core is made of iron and nickel, creating a magnetic field that extends into space and causes the Earth to act like a giant magnet.

Study Notes
Magnetism
- A temporary magnet is a magnet that only exhibits magnetic properties when it is within a magnetic field or has an electric current flowing through it, whereas a permanent magnet retains its magnetic properties even when the magnetic field or electric current is removed.
Earth as a Giant Magnet
- The Earth acts like a giant magnet due to the movement of molten iron in its outer core, which generates a massive magnetic field that surrounds the planet.
Earth Science
- Earth science is primarily focused on studying the composition, structure, and processes of the Earth and its atmosphere.
- A main subtopic within earth science is geology, which deals with the study of the Earth's physical structure, composition, and processes that shape it.
Exclusions and Focus
- Astronomy is an area of study that is NOT included in earth science, as it focuses on the study of celestial objects beyond the Earth's atmosphere.
- A major focus of earth science research is understanding the Earth's natural systems, processes, and phenomena to better manage natural resources, mitigate natural hazards, and predict climate change.
- A key component of earth science studies is the use of scientific methods, including observation, experimentation, and data analysis, to understand the Earth's systems and processes.
