luonnonmagneettikenttä
Luonnonmagneettikenttä, also known as the Earth's magnetic field, is a region surrounding our planet where magnetic forces are exerted. This field originates primarily from the geodynamo, a process involving the convection of molten iron and nickel in the Earth's outer core. The field is dipolar in nature, resembling that of a bar magnet, with a north and south magnetic pole. These poles are not precisely aligned with the geographic poles and drift over time.
The Earth's magnetic field plays a crucial role in protecting life on the planet. It acts as
The strength and direction of the magnetic field vary across the Earth's surface. While the main dipole
