E-Field Charge Separation Rods

The Charge Separation Rods are designed for use with the Lascells E-Field Detector (EL220000). Arrange the rods so that they are touching along an axis. Bring a charged object near one end of the rods and use a pencil or similar to slide the rods apart touching only the feet and not the metal part of the rods. When the charged object is removed test the charge on the two separated rods. If the charged object is negative, electrons are repelled to the rod furthest away leaving the rod closest to the object positively charged. By moving the rods apart the electrons cannot return so the furthest has an overall negative charge and the nearest an equivalent positive charge.
