Magnetic Top System And Method
摘要:
A magnetic top system for energizing, launching, and controlling movement of a spinning top. In one embodiment, a magnetic top launcher may magnetically couple to a top and induce a spinning motion in the top. A top controlling device may magnetically control a traversing movement of the top on a play surface without directly contacting the top.
