Magnetic Field of the Earth

The Earth's magnetic field is like an invisible force field generated by movements within its molten iron core. These movements create electric currents, producing magnetic lines that extend from the planet's interior into space, forming the magnetosphere. This magnetic field protects us from harmful solar radiation and charged particles, helping to maintain a habitable environment. It also causes compass needles to point north, aiding navigation. The magnetic poles can shift over time due to changes in Earth's core, but the overall magnetic field remains essential for life and technological systems.
