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 ...

Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic materials, and where they can attract or repel other magnets. Although we ...

If you need help visualizing magnetic fields ... the intertwining fields of multiple magnets can be beautiful. Perhaps a helix of spherical magnets? What do you have lying around the hosue?

Meanwhile, the magnetic poles are defined as the points where the Earth's magnetic field meets the surface, and are the same ...

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 ...
