What are the primary factors that influence the Earth's magnetic field?

The Earth's magnetic field is generated by the movement of molten iron in its core. This motion creates electric currents, which in turn generate a magnetic field. However, the magnetic field is influenced by several factors, including:

• The Earth's rotation: The rotation of the Earth causes the magnetic field to align along the planet's axis of rotation.
• The Earth's composition: The composition of the Earth's core, mantle, and crust can affect the strength and direction of the magnetic field.
• Solar wind: The solar wind, a stream of charged particles from the Sun, interacts with the Earth's magnetic field and can cause disturbances, such as geomagnetic storms.
• Geomagnetic jerks: Sudden changes in the Earth's magnetic field, known as geomagnetic jerks, can occur due to various factors, such as changes in the Earth's rotation or the motion of the molten iron in the core.
