Abstract

According to embodiments of the present invention, a magnetic coupling structure is provided. The magnetic coupling structure includes a first coupler; a second coupler arranged opposite the first coupler; and at least one non-planar magnetic pillar having a longitudinal axis. One of the first coupler and the second coupler is stationary, and another of the first coupler and the second coupler is movable along the at least one non-planar magnetic pillar to form and adjust a gap between the first coupler and the second coupler along the longitudinal axis.
