The Mova Rotating Antiqued Beige 6 in. diam. Globe is a striking combination of quaint, Old-World map design with futuristic movement. How does it work? Think of how the earth's magnetic field produces countertourque. For this earthly mini-me's motor to get the globe started turning, and to keep it turning, the motor needs a source of countertorque. The globe uses the earth's magnetic field to push against. Think of the needle in a compass. The motor is, in effect, pushing against the needle, which is held stationary by the earth's magnetic field. Fascinating to watch, this globe is a great conversation piece.
