As the digital world demands greater data storage and faster access times, magnetic memory technologies have emerged as a ...

It took 250 years for the Laschamps reversal to take place and it stayed in the unusual orientation for about 440 years. At ...

Explore Maxwell’s equations and their significance in electricity and magnetism, shaping modern technology and science.

The device appeared to violate the conclusion that any conductor at rest with respect to Earth’s surface cannot generate power from its magnetic field,” Princeton’s Christopher Chyba added in a press ...

One way to get moving charges is to run electric current through a wire. (This is literally a stream of electrons.) This will create a magnetic field, and other wires with electric current will ...

All that molten metal conducts electricity, so as it moves it creates an electric current, which in turn generates a magnetic field. As you may recall from Physics 101, a changing magnetic field (like ...

This would create differences in the amount of electrical current from place to place, which, through the laws of electromagnetism, would naturally give rise to a magnetic field. In the new study ...

Magnets and superconductors go together like oil and water—or so scientists have thought. But a new finding by MIT physicists ...

The effect is observed when electrons are subjected to a very strong magnetic field at extremely low temperatures. "The quantum Hall effect is special because the electric currents that are ...

Earth’s rotation also churns up the molten metal, generating electrical currents. Our planet’s magnetic field is similar to that of a bar magnet in that it has a north and south pole ...
