交流アンペール式磁気浮上回転装置によるＡｌ円板の浮上回転実験

  This paper proposes a magnetic levitation and rotation system with the capability of adding alternating ampere force to the eddy current in an aluminum disk and describes results where torque was gained under stable levitation conditions. Specifically, ac electromagnets that generated levitation, centripetal, and ampere forces were arranged to suspend an aluminum disk using three points. Adjusting the angle of the ac electromagnets for centripetal force allowed us to apply part of the centripetal force as torque. Our evaluation of the generation of torque and its dependence on the angle of the magnets and the status of additional ampere force under stable levitation conditions for the aluminum disk is discussed in this paper.
