    Abstract: An axial magnetic cam comprising at least one of a first permanent magnet element supported for rotational motion along an axis provides a continuous, circular magnetic field area path and work-space wherein said path includes a magnetic incline. At least one of a second permanent magnet element having a magnetic field is supported for reciprocating motion within operational proximity of the at least one first magnetic element; wherein said reciprocating motion is substantially parallel with said output axis. The at least one of a first magnetic element. and the at least one of a second reciprocating magnetic element provide a constant magnetic force there between without field cross-over, pass-by, circumvention, or disconnect and without contact of said elements; wherein one continuously follows or actuates the other in response to a motive force; thus greatly reducing or eliminating friction, wear, noise, and complexity.
