The equation for the field in a Halbach sphere is B = 4 3 B 0 ln ( R o R i ) . {\displaystyle B={\frac {4}{3}}B_{0}\ln \left({\frac {R_{\text{o}}}{R_{\text{i}}}}\right).} Higher fields are possible by optimising the spherical design to take account of the fact that it is composed of point dipoles (and not line dipoles). See more A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. This is achieved by having a spatially rotating … See more A Halbach cylinder is a magnetized cylinder composed of ferromagnetic material producing (in the idealized case) an intense … See more • Supermagnet • Permanent magnet • Strong focusing • Inductrack uses Halbach arrays to generate strong fields for maglev See more Magnetization Although this magnetic flux distribution seems somewhat counter-intuitive to those familiar with simple bar magnets or solenoids, the reason for this flux distribution can be intuitively visualised using Mallinson's … See more If the two-dimensional magnetic distribution patterns of the Halbach cylinder are extended to three dimensions, the result is the Halbach sphere.
