Charging an Electrophorus by Induction Using a Negatively Charged Object

A general physics demonstration includes the charging of an aluminum pie plate through the procedure of induction. The demonstration classically includes the subsequent steps.

• Acquire a charged object That is a balloon or Styrofoam plate made of a non-conducting material.
• By Using an insulating handle on the aluminum plate, bring the aluminum plate near to but not touching the Styrofoam plate.
• Touch the rim of the aluminum plate along with your finger.
• Move the aluminum plate away from the charged object.
