Based on the prototype Halbach planar magnet array (HPMA), a honeycomb Halbach flexible permanent magnet array (HHFA) is proposed in this article. HHFA can effectively optimize the magnetic field distribution, increase the magnetic field strength, and reduce the magnetic field distortion. The magnetic flux density distribution for HHFA was obtained through a numerical analytical approach. […]

Effective Medium Transformation: The Case of Eddy Currents in Laminated Iron Cores

Effective medium theory replaces a given fine-scale heterostructure with a homogeneous one in such a way that the physically measurable quantities, e.g., reaction fields and losses, remain approximately the same. This article presents a peculiar case where the physical nature of the problem and the type of governing mathematical equations change upon homogenization. We consider […]
