Abstract

For the bioeffect study of the rotating magnetic fields, a permanent magnet of two layer magic rings driven by a motor was designed to produce a rotating magnetic field with tunable frequency (0-10 Hz) and tunable magnetic flux density (4-300 mT). In the design a simple 3D computing method was adopted to do the optimization. The actual results proved the efficiency of the method. The finished magnet fully satisfied the requirements of the bioelectromagnetic study.
