Give two examples of evidence of the earth's magnetic field.

See the explanation below

Explanation:

The first example is when we can see the aurora borealis, this phenomenon occurs when solar storms are directed toward earth and impact with the earth's magnetic field which serves as a shield for this type of energy coming from the sun. The reaction are colorful lights that can be seen especially in the northern regions of the planet.

The second phenomenon is the migration of birds when there are changes of seasons, they are guided by the orientation of the Earth's magnetic field, due to complex and sensitive organs in their brains, which allows them to orient themselves according to the Earth's magnetic field.

Note: The physicist who proved the existence of this field was Michael Faraday, and years later his assumptions were validated with Maxwell's equations
