Circular Coil On Base, Coil With 94 Turns Of 1 mm Dia, Mounted On A Plastic Base, And Surrounds A Plastic Sheet On Which Iron Fillings Can Be Placed. Used To Observe Static Magnetic Fields Generated By A Constant Flowing Current,For Demonstration On Static Magnetic Fields.
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
