It is not known when humans first noticed the attraction or repulsion between pieces of magnetic material. The first important device depending on these forces was the magnetic compass, which is ...
The National Academies of Sciences, Engineering, and Medicine have been asked to conduct a study on high-magnetic-field science and technology. The primary goal of the Committee on the Current Status ...
Controlling magnetism in a device is not easy; unusually large magnetic fields or lots of electricity are needed, which are bulky, slow, expensive and/or waste energy. But that looks soon to change, ...
MANCHESTER, N.H., July 08, 2024 (GLOBE NEWSWIRE) -- Allegro MicroSystems, Inc. (“Allegro”) (Nasdaq: ALGM), a global leader in power and sensing solutions for motion control and energy-efficient ...
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 of ...
Why there’s a need to assess current-flow distribution. How an arrangement was made for the measurement using a controlled magnetic field, laser-induced current flow, and a subtle physics-materials ...
Allegro’s two new magnetic current sensors enhance system efficiency and protection compared to discrete shunt-based current sensing circuits. The ACS37220 measures current up to 200 A, while the ...
