Abstract: This study presents a novel bearing-less Electromagnetic Reaction Wheel (ERW) design with a Halbach array coil configuration and ferrite cores to overcome weak magnetic fields and start-up ...

We find that the Halbach PM array length and the coil width should be specially optimized to obtain the desired damping coefficient of the power take-off system at a given point absorber dimension.

BARABOO—James M. “Jim” Halbach, age 87, of Baraboo, passed away on Saturday, January 18, 2025, at Oak Park Place in Baraboo. James was born to Gido and Loraine (Mueller) Halbach on March 7 ...

Abstract: Based on the prototype Halbach planar magnet array (HPMA), a honeycomb Halbach flexible permanent magnet array (HHFA) is proposed in this paper. HHFA can effectively optimize the magnetic ...

Phased-array radiofrequency (RF) coils with open access have also been used to improve coverage and signal-to-noise ratio (SNR) for intra-/inter-operative brain MRI [35, 39]. While one would expect ...

A Halbach array is created when smaller magnets are arranged so their magnetic fields are focused in a particular direction and cancel out in another direction. The magnets made by the magnetic ...
