Answer #1

In the attached Figure, we consider two long straight parallel wires carrying currents and in the opposite direction.

Wire #2 will experience a magnetic field due to wire #1 in the direction indicated.  
The direction of indicated shows that wire #2 will be repelled from wire #1. In a similar manner, one can show that wire #1 will experience a force due to the magnetic field of wire #2, and that this force will have a magnitude equal to that of but opposite in direction. Thus, wire #1 will be repelled away from wire #2.
