g Two parallel current with the same direction will (attract or repel) each other. And the two parallel currents with opposite directions will (attract

Explanation:

Two parallel currents flowing in opposite directions tend to repel one another. Contrarily, when two parallel currents flow in the same direction they tend to attract one another.

This is because the direction of the magnetic field on the conductor is usually gotten by applying Fleming's RHR(right hand rule). These RHR then tells us that the direction of magnetic field happens to be opposite to each other. This causes repulsion of the conductors that is carrying current in opposite directions relatively. The same scenario is what happens when current is flowing in the same direction.
