Optimization Method Based on Zonal Harmonics for Axially Symmetric Magnets

An optimization method based on the zonal harmonic description of the magnetic field, suitable for the design of axially symmetric magnetic sources, is presented. Expressions of both axial Bz and radial Bρ components of the magnetic field are obtained as the infinite sum of the zonal harmonics. For arrangements having as the basic building block […]

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. […]
