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 made ...
How can you produce a magnet with exactly the right magnetic field? A research team now has a solution: for the first time, they have created magnets with a 3D printer. Today, manufacturing strong ...
