Purpose: The purpose of this lab is to explore electric charge, electric field and field lines, and electric potential. A computer program is used to visualize these things. Apparatus: A computer and the computer simulation program “EM Field”. Method: We used the “EM Field” program to visualize electric charges (both positive and negative) and electric fields. This allowed us to see the differences in the charges such as how long the electric field vectors are and which way they point. Data: The following table lists the charge, the length of the e-field vector at the distances of 0.5, 1, 2, and 3 units, and the direction of the vectors. Charge 0.5 1 2 3 Direction +1 3 units 1 unit .25 unit 0.1 unit Outward -1 3 units 1 unit .25 unit 0.1 unit Inward +2 6 units 2 units 0.5 unit .25 unit Outward Results: The data shows that the difference in charge as well as the size of the charge affects the electric field vectors. The computer simulation program was very
