1. A method, comprising:
receiving, by an input device from an information handling system, a first instruction to adjust a tension on a damping medium of a linear magnetic ram of the input device; and
adjusting, by the input device, the tension on the damping medium based on the first instruction,
wherein adjusting the tension on the damping medium is performed by a shape memory alloy actuator attached to the damping medium, and
wherein adjusting the tension on the damping medium comprises applying an electric charge to one or more shape memory wires of the shape memory alloy actuator.
