This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

In fact, the discovery actually supports a key part of the theory about how chorus waves work. Using data from the ...

Because Earth's magnetic field is slightly asymmetrical and more complex than that of a regular bar magnet, the magnetic south pole — the point in the Southern Hemisphere where the magnetic ...

And while we’re pretty sure that [Retsetman] didn’t invent it after hitting his head on the toilet, this magnetic gearbox ... a rotor with four pairs of bar magnets on its outer circumference.

They are usually detected in areas of space where Earth’s magnetic field resembles that of a giant bar magnet (a dipole), out to around 51,000 km above Earth’s surface, beyond geostationary ...

The findings have significant implications for studying space weather and the relationship between the Sun and the Earth's ...
