Question

Wire A carries 0.310 A of current to the right. Wire B runs parallel to wire A 7.50 mm away, carrying 0.500 A of current to the left. Both wires are 10.0 m long. a) Do the two wires attract, repel, or neither? _________________

Answer 1

Wire A and Wire B, carrying current in opposite directions while running parallel to each other, will repel each other due to the magnetic forces generated by their currents.

Step-by-step explanation:

When considering two parallel wires that carry electric currents, the magnetic force between them depends on the direction of the currents they carry. According to Ampère's force law, two parallel currents that flow in the same direction will attract each other, while those flowing in opposite directions will repel each other.

In the scenario where Wire A carries 0.310 A to the right and Wire B carries 0.500 A to the left and they are 7.50 mm apart, they are flowing in opposite directions. Consequently, these two wires will experience a repulsive force between them, meaning Wire A and Wire B repel each other.
