What will be the type force between two parallel conductors carrying current in the same direction

What will be the type force between two parallel conductors carrying current in the opposite direction.

Two infinitely long straight conductors carrying current in the same direction are placed parallel to each other. Then

The magnetic field induction at a point due to a current element is given by
