View of a Electrophorous

Electrophorous  (Museum piece:  For generation and storage of especially large electrostatic charges by induction.  Consists of polystyrene plate and an aluminum disk with a polystyrene insulating handle.  The polystyrene base has excellent insulating qualities, thereby storing the generated electrostatic charges over a long period of time.  The disk may be repeatedly charged (by induction) without repeated regeneration.  The base becomes highly charged when rubbed with cat fur.  Plate dimensions are 12 x 12 x 1/8 in. Diameter of pick-up disk is approximately 9-5/6 in., Credit Line: U.S. Military Academy, courtesy of AIP Emilio Segrè Visual Archives
