earth's magnetism
Compass needle's guide
Earth's magnetism is the magnetic field generated by the planet's molten iron core, creating a dipole that orients compasses toward magnetic north.
This field extends into space, shielding the atmosphere from solar wind and charged particles.
The phenomenon explains compass navigation and produces auroras where solar particles interact with the magnetosphere near the poles.
