Magnets and Electromagnetism: Earth as a Magnet

The video explains that Earth acts as a giant magnet with a magnetic field strongest at the poles. This field extends into space, forming the magnetosphere, which protects Earth from solar wind. Charged particles from the sun can cause auroras, visible as northern lights. The video also covers how compasses use Earth's magnetic field for navigation.

• Biosphere

• Lithosphere

• Magnetosphere

• Atmosphere

What is the term for the flow of charged particles from the sun?

• Stellar breeze

• Gamma rays

• Cosmic rays

• Solar wind

What natural phenomenon occurs when charged particles enter the magnetosphere?

• Tornado

• Volcanic eruption

• Earthquake

• Aurora

What is the name given to the aurora in the Northern Hemisphere?

• Polar shine

• Aurora borealis

• Equatorial glow

• Southern lights

How does a compass help in navigation?
