An electronic device is provided. The electronic device includes a first housing, a second housing coupled to the first housing and that performs a sliding operation, a display, of which a size of a visual exposure area is changed in correspondence to the sliding operation of the second housing, a first variable magnetism member disposed at a first location of the first housing, and of which a magnetic force varies depending on a current or a voltage that is supplied thereto, a second variable magnetism member disposed at a second location of the first housing, and of which a magnetic force varies depending on a current or a voltage that is supplied thereto, a magnet member fixed to an inner surface of the second housing, and that moves between the first variable magnetism member and the second variable magnetism member during the sliding operation, and a processor operatively connected.
