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 ...

From galaxies to the Sun, new research explains how turbulent motion can produce large-scale magnetic fields that remain ...

Most of the time, the shape of Earth’s magnetic field is quite similar to that which would be produced by a bar magnet ...

Scientists are mapping the Milky Way galaxy’s invisible magnetic field, revealing how it holds the galaxy together and ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the ...

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 ...
