Heat, Physics
Ring and Ball
Catalogue No: 1060020/2
A simple and economical device for demonstrating the thermal expansion of solids. Comprises an annular brass ring mounted on an insulated handle and a captive brass ball secured to the ring handle through a chain and having diameter just smaller than the internal diameter of the ring. When cold, the ball easily passes through the ring but does not pass on heating. Both ring and ball when heated to the same extent, the ball still passes through the ring showing the expansion of a hole effect. Available in ball diameters:

Ring Launcher
Catalogue No: 1090686
Ring Launcher is also known as electrically powered projectile launcher and it can be used for demonstrating the principles of electromagnetic induction and magnetic force. Using a conducting but non-magnetic aluminum ring, you can show how the alternating current in the electromagnetic coil induces an alternating current in the aluminum ring, which produces a magnetic field opposed to the field of the electromagnetic coil. As a result, the aluminum ring is projected vertically upward. Operates on 220V AC.
