Electric Field Apparatus   (MG-3061)

The apparatus enables electric field patterns to be shown in much the same way that magnetic fields are demonstrated with iron fillings, either by direct viewing or on an overhead projector. The apparatus comprises a clear plastic dish 90 x 12mm dia x depth and base 140 x 125mm, which carries a pair of 4mm socket terminals/electrode holders. Alongside each terminals is a thumbscrew system, which permits fine height adjustment of the electrodes. Six electrodes are supplied, two point source 'two line source' and two circular and two circular rings of 35 and 70mm dia. respectively.

Force on a Conductor balance   (MG-3062)

It is used to demonstrate that when a current is passed through a conductor in a magnetic field, it is subjected to a force of attraction or repulsion depending upon the direction of current in it. It consists of a plastic base 160 x 140mm on which two contact pillars are mounted. Each pillar is provided with an external circuit. A balance 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 1mm, rider of 1 gm weight. With instruction manual.
