Abstract


The purpose of this paper is to investigate possibilities and means that lead to the increase of the magnetic force generated by an actuator with a non-magnetic body levitated in a ferrofluid pre-magnetized by permanent magnets. The numerical simulations outline the components of the structure, dimensions and magnetic constants of materials that render a maximum magnetic force. The experimental measurements effectuated on an experimental model of the actuator are in acceptable agreement with theoretical and simulation results
