Force Between Conductors Demonstrator
An easy and safe way to demonstrate the magnetic force between two current carrying parallel conductors. A cylindrical base, containing a dedicated power supply, supports a rectangular frame. Attached inside the frame are two parallel heavy duty metal tubes supported by fine cone bearings which also supply current to the tubes. The directions of the currents in the tubes can be selected, and movable metal arrows on the frame uprights indicate the current direction in each tube. A push button applies a large current at low voltage to the tubes, which then swing together or apart, depending on whether the tube currents are in the same or opposite directions.

Force On A Conductor Balance
To demonstrate that when a current is passed through a conductor in a magnetic field, it is subjected to attraction or repulsion depending upon the direction of current in it. The apparatus consists of a plastic base 160 x 140 mm on which two contact pillars are mounted. Each pillar is provided with an external circuit. A balanced beam is supported by the pillars on two bearings which form the fulcrum. Two screwed masses are provided in the beam system, one moving vertically for the adjustment of sensitivity and the other moving horizontally for the adjustment of the equilibrium position, when no current is flowing. Scale marked 0 to 75 x 1 mm, rider of 1 gm. weight, with instruction manual.
