The design of magnetic resonance imaging (MRI) gradient coils is a critical element in optimising image quality and system performance. These coils generate spatially varying magnetic fields, which ...

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 ...

Researchers at the National High Magnetic Field Laboratory in Tallahassee, Florida, have pushed a palm-sized superconducting ...

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 ...
