Introduction Electric fields are produced by charges. Charges may be one of two signs, positive or negative. Changing the positions of positive and negative charges can alter an electric field. An electric field is a vector quantity from which the magnitude and direction of an electric force is determined. The electric force is due to the presence of charged particles. Charge is the attribute of matter by which matter responds to electromagnetic forces. Charge is responsible for all electrical phenomena. Charges are either positive or negative.

In Equation 1, w stands for work, q stands for charge, is Coulomb’s constant, r stands for distance from a charge, and stands for the distance over which work is done. The EM Field program was
The magnitude of the field vectors also increase as the magnitude of the charge increases. Vector field lines are tangential to the field lines. If a positive test charge that was free to move was placed inside an electric field, it would follow the field lines toward the negative charge or away from the positive charge. If there is a row of negative charges and a row of positive charges, the field lines between the two rows go toward the negative charges. If the field lines are outside the two rows, they go around the outside of the rows and toward the negative charges. Field lines never overlap. Vectors that were placed on the same field line have the same direction, but the magnitude gets smaller the farther the vector is from the charge. If an imaginary charge was placed on an equipotential line, if it moves with the line, the work would not be zero. This can be determined because the dot product in Equation 1 between and would not be zero. If the charge moved perpendicular to the line, the work would be zero. This can be determined because the dot product in Equation 1 between and would be
