It explains how electrons are accelerated by an electron gun and then deflected by a magnetic field created by Helmholtz coils. The experiment measures the mass of an electron by analyzing the ...

Some of the most fascinating people that you meet at American Physical Society meetings are not actually physicists, and Bruce Rosenbaum is no exception. Based in Massachusetts, Rosenbaum is a maker ...

Abstract: Helmholtz coils are widely used to generate homogeneous magnetic fields. Various parameters influence the magnetic field strength and homogeneity, including coil shape, size, spacing, ...

such as solenoid and Helmholtz coils, cannot control field distribution adequately for practical or clinical applications. In this study, we developed and evaluated a magnetic hyperthermia coil system ...

HelmholtzSim is an open-source Python package for simulating and optimizing Helmholtz coil testbeds ... It leverages the Biot-Savart law for parallel magnetic field calculations, integrates genetic ...

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

Get Instant Summarized Text (Gist) Micrometer-sized, flower-shaped structures made of a nickel-iron alloy can locally enhance magnetic fields by concentrating field lines at their center. The ...

The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications.
