Wikipedia Overview
Barlow's wheel was an early demonstration of a homopolar motor, designed and built by English mathematician and physicist Peter Barlow in 1822. It consists of a star-shaped wheel free to turn, suspended over a trough of the liquid metal mercury, with the points dipping into the mercury, between the poles of a horseshoe magnet. A direct electric current passes from the hub of the wheel, through the wheel into the mercury and out through an electrical contact dipping into the mercury. The Lorentz force of the magnetic field on the moving charges in the wheel causes the wheel to rotate.
The points of the wheel, R, dip into mercury contained in a groove hollowed in the stand. A more rapid revolution will be obtained if a small electro-magnet be substituted for a steel magnet, as is shown in the cut. The electro-magnet is fixed to the stand, and included in the circuit with the spur-wheel, so that the current flows through them in succession. Hence, the direction of the rotation will not be changed by reversing that of the current; since the polarity of the electromagnet will also be reversed.
