Abstract
An example apparatus includes a pointing structure, a magnetic-contrast bearing, and drive circuitry. The magnetic-contrast bearing is coupled to the pointing structure, and includes a magnetic array and a substrate that is arranged with the magnetic array. The drive circuitry generates a magnetic field that interacts with the magnetic array and causes control of a pointing position of the pointing structure.
