What is it called when electric charge is transferred at a distance when objects come in contact with each other's electric fields?

• A. Charging by Conduction
• B. Charging by Friction
• C. Static Electricity
• D. Charging by Induction

Answer: (D)

Charging by induction is charging without direct contact, happening through the influence of a nearby electric field. When a charged object is brought near a neutral conductor, its field causes the charges inside the conductor to rearrange: electrons move toward or away from the near side, creating opposite charge on that surface and the same sign on the far surface. If you briefly connect the conductor to the ground, electrons can flow to or from the earth; when you remove the ground and then separate the objects, the conductor ends up with net charge of the opposite sign to the nearby object. This transfer occurs at a distance, through the field, not by touching. The other methods require physical contact (conduction) or rubbing (friction), and static electricity is the general phenomenon of stationary charges, with induction being the non-contact charging process.
