The Electrophorus is a simple but clever apparatus for demonstrating the process of induction. An excess negative electric charge in the nonconductive insulating bakelite plate is created by rubbing it with fur or wool. Positive and negative charges are separated within the metal ground plate when it comes in contact with the insulating plate. Grounding the top of the dielectric plate leaves it with a net positive charge which can be measured or used to generate sparks. Size of insulting plate: 6" diameter; size of metal ground plate: 3.5" diameter with 5" long attached handle.
