Earth's magnetic field explained
WebWhen the lava came up through a volcano, the rock took a significant time to cool. In this time, the Earth's magnetic field automatically aligned the domains, or atoms, of the lava. Then, when the rock cooled, the atoms were set in place, making the rock magnetic. This is the process that factories use to make bar magnets today. WebApr 5, 2024 · Astronomers have traced a repeating radio signal back to a rocky, Earth-sized exoplanet that appears to have one of the crucial factors that make a world habitable: a magnetic field. The planet is known as YZ Ceti b, and it's orbiting a small red dwarf star located around 12 light-years from Earth.
