ABSTRACT:
A multiple working surface magnetic particle device for transferring torque between two rotatable members is disclosed. The magnetic particle device includes relatively rotatable members defining a gap therebetween containing a magnetically reactive medium. The magnetically reactive medium stiffens in the presence of a magnetic field interlocking the rotatable members. The multiple working surface design allows for a reduction in the size and weight of the magnetic field source resulting in a more compact, lighter weight magnetic particle device.
