A magnetic driving device comprises a slider disposed on an inside of a glass; a
handle disposed on an outside of the glass; a plurality of magnets respectively disposed in the slider and the
handle, the polarities of the adjacent
magnetic poles of the magnets disposed in the slider being opposite to each other, the polarities of the adjacent
magnetic poles of the magnets disposed in the
handle being opposite to each other; and a spacing layer disposed between the adjacent magnets to space the adjacent magnets from each other, the spacing layer being made of a material that is not a
magnet, wherein positions of the magnets in the slider and positions of the magnets in the handle correspond to each other one by one, and the polarities of the
magnetic poles, which are toward the glass, of the magnets in the slider are opposite to the polarities of the magnetic poles, which are towards the glass, of the corresponding magnets in the handle, respectively.
