1. A magnetically-assisted mechanical power transmission system, the system comprising:
a first component having first formations arranged along the first component;
a second component having second formations arranged along the second component, wherein one of the first component and the second component is a first rotating component;
a first magnetomotive force (MMF) source that generates a first magnetic flux, wherein the first MMF source either is at least indirectly supported in relation to, or is formed as part of, one or both of the first component and second component; and
a magnetic circuit in which the first magnetic flux generated by the first MMF source is communicated via the first and second components, which provide first and second reluctances, respectively, and at least one of an additional structure or air gap that provides an additional reluctance,
wherein the first component is in contact with or in proximity to the second component so that, in response to a first movement of the first component in a first direction, the second component is driven to undergo a second movement in a second direction,
wherein at least a first portion of the first magnetic flux is communicated between at least one of the first formations of the first component and at least one of the second formations of the second component so that one or more magnetic forces are exerted between the first component and the second component, and
wherein, when the first movement of the first component is changed from being in the first direction to being in a third direction opposite the first direction, then the second component is driven by the one or more magnetic forces so that the second movement is changed from being in the second direction to being in a fourth direction opposite the second direction,
wherein a first amount of backlash movement between the first component and the second component is avoided or reduced due to the one or more magnetic forces.
