ABSTRACT:
A display apparatus utilizes magnetic interaction to achieve suspension and electromagnetic interaction to maintain continuous motion. The display apparatus has a base assembly including an anchoring point, and a plurality of spaced first magnets disposed in spaced relation relative to the anchoring point; a suspension member including a longitudinal axis, opposite two ends, a second magnet, and a radially disposed third magnet member, and wherein the first magnets are operable to magnetically support the suspension member in a suspended state; a tether for tethering the suspension member to the anchoring point; and an electromagnet for electromagnetically impelling the third magnet member when the suspension member is rotated about its longitudinal axis thereby maintaining the rotation of the suspension member.
