Abstract
A magneto-fluidic seal includes a shaft, a pole piece, and a plurality of sealing fluid rings located between the shaft and the pole piece. The sealing fluid rings may be defined by the shaft and/or the pole piece and contain a ferromagnetic fluid. At least one channel having a bottom is defined by either the shaft or the pole piece. A shunt is located directly adjacent to the bottom of the channel. The thickness of the shunt is based on the energy differential in the plurality of sealing fluid rings as the fluid is displaced from one side of the sealing fluid rings to the other side of the sealing fluid rings.
