Back to 22.10 Magnetic Force between Two Parallel Conductors

22.10 Exercise 1

Avg difficulty 2.5

Two parallel wires carry equal currents in the same direction and are separated by a small distance. What is the direction of the magnetic force exerted by the two wires on each other?

  1. No force since the wires are parallel.
  2. No force since the currents are in the same direction.
  3. The force is attractive.
  4. The force is repulsive.
