Question

When does the force acting between two parallel and straight current carrying conductors become (i) attractive and (ii) repulsive and why?

Hint:

Parallel currents attract, anti-parallel currents repel due to the interaction of magnetic fields.

Answer 1

(i) Attractive: When the currents flow in the same direction. (ii) Repulsive: When the currents flow in opposite directions. \[ \boxed{\text{Attractive if same direction, repulsive if opposite direction.}} \]
