Like most planets in our solar system, the Earth has its own magnetic field. Thanks to its largely molten iron core, our planet is in fact a bit like a bar magnet. It has a north and south magnetic ...

The physical processes behind the two phenomena are different. When heated, a permanent magnet loses its magnetism because its relatively well-aligned magnetic domains, which are tiny magnets, get ...

Discover how ordinary metals are transformed into powerful magnets, exploring natural and artificial magnet creation ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...
