Deicing of an external mirror (10) on a vehicle is effected by applying a sudden deformation force to the mirror. Sandwiched between the mirror (10) and a mounting surface (12) is a structure that includes a ribbon conductor (14), portions of which overlap each other in such a way that current through the conductor passes through these portions in opposite directions. A capacitor (32) is discharged through the conductor (14), generating a magnetic field that results in mutual repulsion between the overlapping portions. The mounting surface resists this repulsion force, which is instead transferred to the mirror (10), causing momentary distortion, and dislodgment of ice on the mirror surface. The same technique is also applicable to deicing of windows.
