Explanation

The instrument used for securing a large number of similar charges by induction is called an "Electrostatic Induction Machine" or simply an "Induction Machine." This device is commonly used in electrostatic experiments and demonstrations to accumulate a significant amount of electric charge on a conductor by the process of induction. It's a way to transfer and accumulate electrical charge on an object without direct contact with a charge source.
