Question

Why do two long current carrying conductors attract when the currents are parallel?

Answer 1

When two conductors are carrying current in the same direction - they are attracted towards each other because of opposite magnetic poles created between them. They repel when they carry current in opposite directions.

When the currents move in opposite directions the eletromagnetic force causes them to repel each other in a similar way.
