1. A magnetic actuator comprising:
one or more coil members configured to generate an asymmetrical field distribution; and
a moveable object, wherein the magnetic actuator is configured such that one or more of a position of the moveable object, a speed of the moveable object, or a direction of movement of the moveable object is controllable based at least on the generation of the asymmetrical field distribution;
wherein the moveable object comprises a rotatable member configured to rotate around a central axis of rotation;
wherein the rotatable member comprises a set of bobbins attached thereto, and wherein the one or more coil members comprise a first coil member, the first coil member comprising a plurality of windings wound on the set of bobbins;
wherein the set of bobbins comprises a first bobbin, and wherein the windings circumscribe an axis at the first bobbin; and
wherein the set of bobbins have a linear arrangement over a surface of the rotatable member, and each additional bobbin in the set of bobbins has progressively fewer windings wound thereon relative to a preceding bobbin the farther the additional bobbin is from the first bobbin.
