Abstract: A magnetic curtain and a sliding panel formed therefrom are revealed. A magnetic curtain includes an upper portion, a lower portion, a plurality of a plurality of middle portions arranged between the upper portion and the lower portion, and a plurality of magnetic parts disposed on an interface between two adjacent portions of the magnetic curtain. While the magnetic curtain is retracted, the two adjacent middle portions are folded in half in turn to form a curved part respectively. The two adjacent curved parts are away from each other so as to prevent protrusion and extension caused by overlapping of the curved parts. Thus the magnetic curtain has more applications and higher use efficiency.
