Final answer:
The answer to the question is (A) The wires attract each other if the currents are in the same direction, and (D) The force between the wires depends on the distance between them.
Step-by-step explanation:
The magnetic force between two long, straight parallel wires carrying currents depends on the direction of the currents. If the currents are flowing in the same direction, the wires attract each other. This is because the magnetic field lines produced by one wire will interact with the current in the other wire, resulting in an attractive force.
For example, if wire 1 is carrying a current I and wire 2 is carrying a current 2I, the magnetic field lines produced by wire 2 will act on the current in wire 1, resulting in an attractive force.If the currents are flowing in opposite directions, the wires repel each other. This is because the magnetic field lines produced by one wire will oppose the current in the other wire, resulting in a repulsive force.
The question pertains to the magnetic interaction between two parallel currents in wires. According to the right-hand rule (RHR-1), when two parallel wires carry currents in the same direction, they will exert an attractive force on each other. Conversely, if the currents flow in opposite directions, the wires will exert a repulsive force on each other. Additionally, the force between the wires does indeed depend on the distance between them; the force is inversely proportional to the distance, so the closer the wires are, the stronger the force they exert on each other. Therefore,
