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 ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

An exotic state of matter has been found lurking within a previous exotic state which had discovered in a magnetic compound ...

All magnets also have north and south poles, and when the north pole of one magnet is exposed to the south pole of another ...

The first known reference to magnetism dates ... creating an overall magnetic field. When you bring a strong magnet near an iron nail, it can temporarily force the domains inside the nail to ...

Seeking to mimic self-assembly processes that occur naturally, RIKEN researchers have demonstrated that the self-assembly of ...

Using an XMC1100 microcontroller development board and a TLV49 3D magnetic sensor, the device is able to track the poles of a magnet in real-time and produce an approximation of what the field ...

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 ...
