NASA monitors the South Atlantic Anomaly, a growing magnetic field disturbance affecting satellites and spacecraft.

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 updated version of the World Magnetic Model was released on Dec. 17, with a new prediction of how the magnetic north pole will shift over the next five years. Here's why it was changed.

Indeed there is, in addition to the obvious ways to manipulate the spin using magnetic fields, an indirect effect on the electron spin from externally applied electric fields, due to the so-called ...

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 ...

In an electric motor, a magnetic field helps an internal coil to spin. This might be used to drive an axle and turn the wheels of an electric car, for example. Higher grade magnets mean motors ...

HONG KONG (8 December 2024)—A new vortex electric field with the potential to enhance future electronic, magnetic and optical devices has been observed by researchers from City University of ...

In ferromagnetic materials such as iron, which respond strongly to magnetic fields, the electrons all spin in parallel with their neighbours. In antiferromagnetism, the other established type of ...

It occurs when a material carrying an electric current is exposed to a magnetic field, producing a voltage perpendicular to both the current and the magnetic field. This effect has been ...
