Two long,current-carrying wires run parallel to each other.If these wires tend to push away from each other,the currents in them must be in opposite directions.

Question

Quizplus · Accepted Answer

According to the right-hand rule, if the wires are pushing away from each other, the magnetic field created by the currents in each wire is in the opposite direction. Therefore, the currents in the wires must be in opposite directions as well.
