Study of a ferrofluid actuator with levitating nonmagnetic disc

The paper presents a ferrofluid actuator with a nonmagnetic disc, whose position can be controlled by a command current in the surrounding coils. An exact analytical expression for the force acting on the nonmagnetic disc is determined for a simplified model, and a numerical analysis based on FEM is...
