Abstract
A magnetic shear force transfer device for transferring shear forces across a non-magnetic gap includes a first magnetic structure comprising concentric circular tracks of magnetic sources magnetically printed into a first magnetizable material a second magnetic structure comprising concentric circular tracks of magnetic sources magnetically printed into a second magnetizable material. Each concentric circular track has an even number of magnetic sources where adjoining magnetic sources alternate in polarity. One or more tracks of the first magnetic structure are rotated relative to one or more tracks of the second magnetic structure such that a maximum torque condition coincides to one angular orientation between the first and second magnetic structures.
