Answer Details
The instrument used for securing a large number of similar charges by induction is called an electrophorus. An electrophorus consists of two parts: a metal plate and a non-conducting plate, usually made of plastic. The metal plate is charged by rubbing it with a fur or other material, which causes a buildup of negative charge on the plate. When the non-conducting plate is placed on top of the metal plate, the negative charge on the metal plate induces a positive charge on the top of the non-conducting plate. This process can be repeated multiple times, resulting in a large number of charges that can be used for various experiments or applications.
