A positive charge or a negative charge is said to make its field around itself. If a charge particle Q1 exerts a tension on charge Q2 placed near it, it may be stated that as Q2 is in the space of Q1, it finds some force, or it may also be said that as charge Q1 is inside the field of Q2, it experience some force. Therefore space around a charge in which another charged particle experiences a force is said to have electrical field in it.
