A permanent magnet 54 mounted on rods 41 passes vertically over a conductive plate 56 in an elevator hoistway 36, a reactive force causes movement of the permanent magnet 54 vertically away from the conductive plate 56 so that a wedge 24 secured to the rods 41 moves within a tapered wedge guide 44 until it contacts an elevator guide rail 14 on which an elevator car 2 is riding, thereby braking the elevator car 2.
