Diamagnetic levitation of graphite-epoxy composite plates.

Caption

a Schematic illustration of a graphite-epoxy diamagnetic plate stablylevitated above an array of cubic Nd2Fe14B permanent magnets with alternating magnetization. b Top view of a stably levitated composite plate (length of 38.2 mm, width of 29.1 mm, thickness of 1.0 mm, and mass of 1.58 g) positioned next to a quarter (coin in the United States) for comparison. Inset displays a zoomed-in view of the dielectric mirror mounted on the levitated device. c Side view of the levitated composite plate showing a levitation height of 50 μm. d Side view of the device demonstrates three-dimensional (3D) trapping of the levitated plate through a balance of vertical and lateral diamagnetic forces combined with gravitational force. Scale bars in (b) and (c) are 10 mm
