What is charging by induction?​

Answer:

Charging by induction is a method used to create a charge in an object without making direct contact with a charged object. It involves rearranging the charges within an object to create a region of positive or negative charge.

Charging by induction is a method of charging an object without direct contact. It involves bringing a charged object close to a conductor, which polarizes the charges within the conductor and induces a charge separation. The charged object then induces an opposite charge in the conductor, which allows the conductor to become charged without direct contact. This process is commonly used in devices such as wireless charging pads for smartphones and electric toothbrushes.

(explanation)

Charging by induction is a method of charging an object without direct contact using the principle of electrostatic induction. This involves bringing a charged object close to the uncharged object, causing a redistribution of charges, and creating opposite charges on the surfaces of the uncharged object, which effectively charges it.
