Imanes y electromagnetismo: la tierra como un iman

The video explains that Earth is like 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. A compass, with its magnetized needle, aligns with Earth's magnetic field, aiding navigation.

What are the names of the auroras visible in the Northern Hemisphere?

Describe how a compass works in relation to the Earth's magnetic field.
