If two identical wires carrying a certain current in the same direction are placed parallel to each other, they will experience a force of repulsion.
true / false.

Explanation:

When there is an electric current flows in a wire then a magnetic field is set up in the another wire and it experiences a magnetic force and similarly another wire also experiences a force. The direction of force is given by Fleming left hand rule which shows that both the wires attract each other if the direction of current is same in both the wires.
