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.
