Two parallel conductors carrying unequal currents in the same direction............ (a) neither attract nor repel each other (b) repel each other (c) attract each other (d) will have rotational motion.

Answer: (c). Currents in the same direction always attract, whatever their magnitudes. Unequal currents only change the size of the force, which is equal and opposite on the two wires (Newton's third law). So the answer is (c) attract each other.

Force on Current-Carrying Conductors

Two parallel conductors carrying unequal currents in the same direction ............

Show answer and solution

Answer: (c)

Currents in the same direction always attract, whatever their magnitudes.
Unequal currents only change the size of the force, which is equal and opposite on the two wires (Newton's third law).
So the answer is (c) attract each other.
