Today, the magnets used in nuclear magnetic resonance (NMR) and medical magnetic resonance imaging (MRI) represent the primary commercial applications of superconductivity. NMR, used mainly in the ...

Stellarators, twisty machines that house fusion reactions, rely on complex magnetic coils that are challenging to design and build. Now, a physicist has developed a mathematical technique to help ...

Little Big Coil: the record-breaking magnet is the size of a toilet roll core. (Courtesy: Stephen Bilenky/National MagLab) The highest continuous magnetic field ever created in the lab has been ...

This file type includes high resolution graphics and schematics when applicable. Generating a high-frequency magnetic field can be quite a challenge due to an assortment of technical issues. At high ...

In this article, I want to use an MRI (magnetic resonance imaging) medical scanner design as a familiar example for what needs to be done in a power supply design architecture to allow it to function ...

• Magnetostrictive material harvests energy by producing a magnetic field in response to a mechanical load. • Magnetostrictive material called Galfenol can be machined and formed into shapes to handle ...
