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 ...

much the same way iron filings can reveal the magnetic field around a magnet. The team thinks that the measured three-dimensional structure might create strong turbulence within the protoplanetary ...

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

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

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 ...

Scientists know well how conventional materials conduct heat. However, things are not as straightforward under extreme ...

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 ...
