MAGNETIC FIELD OF TUBULAR LINEAR MACHINES WITH DUAL HALBACH ARRAY [PDF]
Progress In Electromagnetics Research, 2013 Permanent magnet (PM) array afiects ∞ux fleld distribu- tion of electromagnetic linear machines signiflcantly. A novel dual Halbach array is proposed in this paper to enhance ∞ux density in air gap, and thus to improve output performance of linear machines.

Three-Dimensional Magnetic Field Modeling of a Cylindrical Halbach Array [PDF]
IEEE Transactions on Magnetics, 2010 A semi-analytical description of the 3-D magnetic field distribution of a cylindrical quasi-Halbach permanent magnet array is derived. This model avoids the necessity of time-consuming finite element analyses and allows for fast parameterization to investigate the influence of the number of segments on the magnetic flux density distribution.

The efficiency and the demagnetization field of a general Halbach cylinder [PDF]
, 2015 The maximum magnetic efficiency of a general multipole Halbach cylinder of order $p$ is found as function of $p$. The efficiency is shown to decrease for increasing absolute value of $p$. The optimal ratio between the inner and outer radius, i.e.
