This fascinationg toy is build with magnetic top and plate with built in some magnets. Magnetic field generated by these magnets is such, that top can levitate about 3 cm over the surface of the plate.

This time we met with a zone, where magnetic fields (acting up) are compensated with gravitational forces (acting down). Balance of the top is conserved thanks to giroscope effect created due to its rotation (angular momentun conservation). Levitation of the top is long due to neglecting friction of the air.
