earth's magnetic field

Earth’s Magnetic Field is also known as Geomagnetic Field.

It extends from the Earth’s interior to where it meets the Solar wind, a stream of charged particles emanating from the Sun.

Earth’s magnetic field serves to deflect most of the solar wind.

Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind. This is a stream of charged particles leaving the Sun's corona and accelerating to a speed of 200 to 1000 kilometres per second. They carry with them a magnetic field, the interplanetary magnetic field (IMF).

The area of space near an astronomical object in which charged particles are controlled by that object's magnetic field.

It is a donut-shaped region containing low-energy charged particles that could be found inside the Magnetosphere.

The distance at which a planet can withstand the solar wind pressure is called the Chapman–Ferraro distance.

The area of the magnetosphere wherein the pressure from the planetary magnetic field is balanced with the pressure from the solar wind.

Opposite the compressed magnetic field is the magnetotail, where the magnetosphere extends far beyond the astronomical object.
