the metalic wires are lying parallel. if the current in these wires be flowing in same direction, the wires will

Explanation

When two parallel wires carry current in the same direction, they attract each other (a). This phenomenon occurs due to the magnetic fields generated by the current flow.Here's the explanation:Current flow creates magnetic field: When a current flows through a conductor, it creates a magnetic field around the conductor. The direction and strength of this magnetic field are determined by the right-hand rule.Magnetic fields interact: When two parallel wires carry current in the same direction, the magnetic fields they create interact with each other. In this specific case, the magnetic field lines generated by each wire loop in the same direction around the other wire.Right-hand rule again: Applying the right-hand rule for magnetic forces, the fingers of your right hand curl in the direction of the current flow, and your thumb points in the direction of the force exerted by the magnetic field. In this case, the magnetic fields of each wire exert a force towards the other wire, resulting in an attraction.
