Nova Electronic Perpetual Motion

This mobile uses both poles of a magnet. For example, whether or not it has a battery, the largest magnet keeps the mobile still while at rest. Add the battery and give the mobile a soft push with a finger and the repellent movement begins. An unobstructed mobile on a flat surface will stay in constant motion as long as the magnetic coil in the base has a battery-powered DC current.
