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

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.

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

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 ...

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 ...

Graphene, which is comprised of a single layer of carbon atoms arranged in a hexagonal lattice, is a widely used material ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field ...

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 ...

Throughout any given year, the National Academies convene hundreds of conferences, workshops, symposia, forums, roundtables, and other gatherings that attract the finest minds in academia and the ...
