In a remarkable leap for quantum physics, researchers in Japan have uncovered how weak magnetic fields can reverse tiny ...

A series of buzzing, bee-like “loop-currents” could explain a recently discovered, never-before-seen phenomenon in a type of quantum material. The findings from researchers at CU Boulder may one day ...

A magnet produces a vector field, the magnetic field, at all points in the space around it. It can be defined by measuring the force the field exerts on a moving charged particle, such as an electron.

A weak zone in Earth’s magnetic field, known as the South Atlantic Anomaly, has expanded at an alarming rate over the past ...

From symmetry considerations and the right-hand rule, H must be in the direction shown in the figure. That is To evaluate the line integral in Ampere’s law, we choose a rectangular Amperian path ...

The Danish physicist Hans Christian Oersted was discussing in the year 1820 about the possibility of electricity and magnetism being associated to one another, and in the process presenting it finally ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Allegro has added magneto-resistive sensors to its Hall-based range of current and magnetic field devices, for high-sensitivity high-bandwidth applications. The first product is a 5A 1MHz isolated ...
