What is the Magnetic Field Of Earth?

Earth Magnetic field also known as the geomagnetic field is a powerful and complex field that surrounds the planet and extends into space.
The magnetic fields are generated by swirling iron in the Outer Core, which acts like a huge dynamo.

   

The magnetic field is tilted at an angle of about 11 degrees relative to Earth's axis of rotation, and has a north and south magnetic pole that are located near the geographic North and South Poles, respectively. However, the magnetic poles do not exactly align with the geographic poles and they also move slowly over time.

The strength of Earth Magnetic field varies at different points on the surface of the planet, with the field being strongest near the poles and weakest near the equator. The strength of the magnetic field is measured in units of Gauss (G) or Tesla (T), with one Gauss equal to 0.0001 Tesla.

Earth Magnetic field is important for many reasons. It helps to protect the planet from harmful solar and cosmic radiation, and also plays a role in the behavior of charged particles in Earth's atmosphere and magnetosphere. Additionally, Earth Magnetic field has practical applications in navigation, communication, and many other fields.
