Magnetic Resonance Imaging (MRI) relies on the precise performance of gradient coils to achieve high spatial resolution and rapid imaging sequences. These coils generate spatially varying magnetic ...

High frequency Helmholtz coils are often used to generate uniform but time varying high frequency magnetic fields for a number of applications such as magnetic field susceptibility, calibration, and ...

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 ...

One problem with high frequency magnetic design is how to sort out the losses that contribute to a part's efficiency. With the exception of dc resistance, these losses are very difficult to separate ...

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 ...

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 ...

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 ...

Scientists are pursuing the proposition of clean and inexhaustible power from nuclear fusion through a variety of experimental reactor designs, and one of the more interesting examples is a roughly ...
