What does the northern lights have to do with magnetism?

The northern lights, or auroras, are closely related to magnetism as they occur when charged particles from the sun interact with the Earth's magnetic field. These solar particles are funneled towards the poles by the magnetic field, colliding with gases in the Earth's atmosphere and producing stunning displays of light. This phenomenon highlights the complex relationship between solar wind, magnetism, and atmospheric conditions, making it a beautiful manifestation of Earth's magnetic protection against solar radiation.
