Oersted's Apparatus, demonstrates the action of electric current on a magnet. A cobalt steel needle (75mm long) with agate bearing supported by pivot, mounted on a plastic base and surrounded by rectangular frame fitted with terminals, 0.6 lbs, 8.0x7.5x1.8in
Racing Rings consists of three rods one each of copper, aluminum and PVC, Ring magnet is dropped down the PVC rod, it falls unobstructed, Two metal rods create an induced magnetic field to that adds resistance to the rings travel, metals are different, they fall at different rates
Air core solenoid, coils wound on a plastic tube with approximately 575 turns of copper wire, can carry a current of 5A continuously or 10A intermittently.
Tangent Galvanometer, Features copper magnet wire, adjustable potentiometer, compass and non-magnetic stand. Measure an electric current by determining the magnitude and direction of the horizontal component of Earths magnetic field
