Provided is an electromagnetic induction potentiometer adaptive for full-stroke detection, including a movable element configured to obtain an input for position change, a permanent magnet attached to the movable element, a magnetic induction sensor configured to sense positions of the permanent magnet and generate an initial potential signal, and an full-stroke adaptive output adjusting unit configured to collect the initial potential signal and adaptively adjust the initial potential signal to an actual potential signal corresponding to a full stroke of position changing of the movable element.
