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 ...

The new magnet is capable of creating a magnetic field of 42.02 tesla, which is more than 800,000 times stronger than the Earth’s and beats the 41.4 tesla record set by the US National Magnetic ...

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 ...
