As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while ...
The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei ...
When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused ...
Passive maglev uses permanent magnets in a specific configuration to create a constant magnetic current that levitates the pod, similar to the magnets you might've played with as a kid.
