Abstract
This paper describes a permanent magnet with an external circular magnetic field (poleless permanent magnet) and its properties, as well as a method for its creation. The magnet generates a strong external azimuthal magnetic field around a cylinder of a magnetically hard high-coercivity material, such as NdFeB, SmCo, AlNiCo or hard ferromagnetic ceramics. The field has a circular (azimuthal) geometry, not a dipole. There are no pronounced north and south poles. Maxwell's law ∇.B  = 0 is not violated. The field strength is proportional to the remanence Br of the material, the geometric dimensions of the cylinder (diameter, length) and its reversed magnetic permeability µrec.
