WebF / l is the force per unit length between two parallel currents I1 and I2 separated by a distance r. The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the pinch effect in electric arcs and plasmas. The force exists whether the currents are in wires ... WebThe direction of an electrical field at a point is the same as the direction of the electrical force acting on a positive test charge at that point. For example, if you place a positive test charge in an electric field and the charge moves to the right, you know the direction of the electric field in that region points to the right. WebJan 24, 2024 · Mathematically, the electric field at a point is equal to the force per unit charge. It is a vector quantity, i.e., it has both magnitude and direction.
