Electric Field Apparatus

The apparatus ebles electric field patterns to be shown in much the same way that the magnetic fields are demonstrated with iron filings . The apparatus comprises a clear plastic dish 90 x 12mm diameter x depth, and base 140 x 125mm, which carriers a pair of 4mm socket termils/ electrode holders.A long side each termil is a thumbscrew system which premits fine hight adjustment of electrodoes.Six electrodsare supplied, two point source two line source' and two circular rings of 35and 70mm diameter respectively.
