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.
