A novel double-action actuator based on ferrofluid and permanent magnets

In this article, an electromagnetic actuator with a movable non-magnetic disc immersed in a ferrofluid that is exposed to a non-uniform magnetic field generated by permanent magnets is presented. The position of the levitated disc is stably controlled by the current in a command coil. Numerical simu...
