Rotation of magnets with liquid mercury

Описание к видео Rotation of magnets with liquid mercury

An experiment invented by Ampère, shows the repulsion between the parts of the same flow. He had designed the following device: in a wooden base are two grooved circles filled with mercury. The conductor floating on the mercury creates a connection in the mobile part. If a high current is passed in this condition the mobile part of the conductor moves away from the starting point of the current and a movement is created. By increasing the voltage, the rotation speed changes. Working voltage 2.8 DC inverter.
