Abstract
A track element of a non-contact bearing extending in a length direction. The track element includes a conductive material strip having a facing surface with a height and width and a rear surface opposite the facing surfaces. The conductive material strip includes a slit extending in a height direction to form a first leg and a second leg, in which the first leg is bent in a zig-zag shape and the second leg is bent in a zig-zag shape that is complementary to the bending of the first leg. When the conductive material strip is viewed in a direction parallel to the facing surface, the first leg and the second leg cross each other at least once.
