This video explores the nature of magnets and how they create invisible magnetic forces. It explains the origin of magnetism, how magnetic fields are formed, and the role of electrons in generating ...

For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon ...

External sources, such as the early solar wind or Earth’s magnetic field, were too weak or faded too early. Internal sources like a magma ocean or mantle-core precession might have helped, but ...
