Give this top a spin and watch it move for hours without stopping. Secret Revealed: The top contains a small magnet. When this magnet moves past the center of its base, the top's spinning magnetic field induces a current in a coil, which closes a switch, allowing a battery to momentarily energize a small electromagnet. The top increases its rate of spin and moves away from the center of the base. Top: 2.5 cm (1.0 in), Base: 8.0 cm (3.1"), (Note: 9-volt battery not included)
