Magnetic flux generated by neodymium-iron-boron magnets of three different configurations are calculated and compared by using COMSOL Multiphysics simulation. For a magnetic ring, the substantial flux density of 0.6-0.7 T is obtained in the bore and the edge. The values are increased beyond 1 T in the gap between inner and outer concentric rings in the second structure. The magnetic flux density is fairly uniform in the circumferential direction. Finally, moderate fields around 0.6 T in spaces between magnetic bars arranged into concentric arrays can be utilized. In this structure, the magnetic flux density along the radial direction measured from the center of the ring peaks at two distances corresponding to two arrays of magnets. These different profiles of magnetic field can be implemented in devices and experiments of different requirements. [ABSTRACT FROM AUTHOR] |
