Two insulated current-carrying straight wires of equal length are arranged in the lab so that Wire A carries a current northward and Wire B carries a current eastward,the wires crossing at their midpoints separated only by their insulation.Which of the following statements are true?
A)The net force on Wire B is southward.
B)The net force on Wire A is westward.
C)There are no forces in this situation.
D)There are forces,but the net force on each wire is zero.

Question

Quizplus · Accepted Answer

Each wire produces a magnetic field that exerts a force on the other wire due to their currents. However, these forces are equal in magnitude and opposite in direction, resulting in a net force of zero on each wire. Therefore, D is the correct choice.
