Magnetic and electric field lines are in many ways similar, with few crucial differences. Which of the properties listed below does NOT apply to both fields? O All of these properties apply to both E and B field lines. The density of lines is proportional to the field strength in that area. Field lines never intersect. Tangent to the line at a point gives you the direction of the field as that point. O Field lines form closed loops.

How to solve this question
Consider the seven current-carrying wires and the four closed paths shown in the figure. For each of these paths (C1, C2, C3, and C4) determine the following in terms of ?0. Use standard sign convention for the currents; minus is down into the page and positive is up out of the page. (Assume I1 = 2.00 A, I2 = 2.00 A, I3 = 5.00 A, I4 = 6.00 A, I5 = 5.00 A, I6 = 6.00 A, and I7 = 7.00 A.)
