The Earth's magnetic poles are the points at which the magnetic field lines of the Earth's magnetic field enter and exit the Earth. Magnetism is the property of certain materials to attract or repel each other, and is caused by the moving electrons within those materials. The Earth's magnetic field is generated by the motion of molten iron in the Earth's outer core, which creates electric currents that produce the magnetic field. The magnetic poles play a crucial role in Earth's magnetic field, as they are the locations where the field is the strongest and where compasses point. They also protect the Earth's atmosphere from solar wind and cosmic rays, which can strip away the atmosphere and harm life on Earth.
