Magnetic North – Magnetic North Pole

What is the magnetic field, anyway? Earth’s core is made of molten iron, and that geothermal energy is what keeps us warm, gravitized, and protected from the sun’s unrelenting radiation. As molten iron swirls, rises, is cooled, and falls back into the center, the convection (or circulating heat, the same as a convection oven) powers continental drift and also generates the magnetosphere.
