Question

why two parallel metallic wires carrying current in opposite direction repel each other ?

Answer 1

A moving charge is a current so it will produce a magnetic field. Between the wires, the magnetic fields from the two wires point in the same direction sothe resulting or total magnetic field will be large. ... Q4 Explain why two parallelwires carrying currents in opposite directions repel each other.

Answer 2

Once the magnetic field has been calculated, the magnetic force expression can be used to calculate the force. The direction is obtained from the right hand rule. Note that two wires carrying current in the same direction attract each other, and they repel if the currents are opposite in direction.
