Electric Field Apparatus

Description

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 12 mm diameter x depth, and base 140 x 125 mm
Alongside each terminal 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 rings of 35 and 70 mm dia. SP4-1321
