What are the types of non-contact forces?

The three main types of non-contact forces are :

1. Gravitational force: It is the attractive force which acts between two or more than two bodies till infinity due to their masses. For example: the Earth pulls all objects towards its center.
2. Magnetic force: The force exerted by a magnet. For example: A magnet attracts iron objects without touching them.
3. Electrostatic force: The force exerted by a charged body on another charged or uncharged body is known as electrostatic force. For example: A charged comb attracts small pieces of paper even without contact.
