because

Explanation:

Answer 2

Answer:

Two parallel conductor carrying current in the opposite direction repel each other because the magnetic field through the conductor is defined by the fleming's right hand rule.

Because of this the directions of magnetic field are opposite and cause the repulsion in current carrying cobductor or in wire which is oppsitely placed.

If the currect carrying conductor in which the flow of current in same direction then the wire attracts each other.
