The problem of magnetic clutches is addressed by this paper. Specifically, the effect of permanent magnet magnetization patterns on shear force production is investigated. Dual-facing magnet structures and magnet-and-steel structures (with and without current) are evaluated by finite element techniques. Shear force production is shown to be strongly affected by magnetization patterns as well as geometric sizing.
