Wheel Rotation

| View Cart ⇗ | Info

“Rotation of a Wheel. The same force which throws the wire away from the mercury, will cause the rotation of a spur-wheel. For this purpose the conducting wire, instead of being suspended, as in the former experiment, must be fixed firmly to the arm. A support for the axis of the wheel may be made by soldering a short piece to the side of the conducting wire, so as to make the form of a fork, the lower end of which must be flattened with a hammer, and pierced with fine orifices, o recieve the ends of the axis.” —Comstock, 1850
