Abstract
An information handling system peripheral mouse accepts scroll inputs at a scroll wheel extending from the upper surface of the mouse. The scroll wheel rotates about an axis and has a chamber inside a the wheel that is filled with MR fluid having particles that interact with a magnetic field so that the viscosity of the fluid varies based upon the presence of a magnetic field. A sliding magnet carrier moves magnets relative to the scroll wheel to adjust the MR fluid viscosity and the amount of haptic feedback created at blades within the chamber that resist the passage of the MR fluid.
