| A magnetic end effector utilizing a switchable Halbach array includes a pair of opposing members that can move towards and away from each other. The switchable Halbach arrays are located on or near the inner surface of the opposing members. A mechanical switching system is used to control the switchable Halbach arrays by moving one or more magnets that make up the switchable Halbach arrays. When manipulated in a certain way, the switchable Halbach arrays cause the opposing members to move towards each other, and when manipulate in a different manner, cause the opposing members to move away from each other. | ||||||
