User Introduction Assignment of Electromagnetism: Magnetic Effect of a Current on wires

Hello BIT 3rd fellows.
Asalamo Alaikum.
How are you all..
Hope fine.
------------
last lecture main Sir nay aik chhoti si assignment kahi thi.
Humain karna yeh tha kay...Sir kay aik question ka answer search kar kay ana tha..

Question:

( What happens if two current-carrying wires come near each other?having same current and same direction)

Agar 2 cables main say same current same direction main pass kar raha hon tu.
kiya yeh dono cables aik dosaray ko repel karain gi ya , attract karain gi?

As the two wires of the above diagram move together, their flux lines overlap:

This effectively strengthens the magnetic field in between the two wires. Remember though, the diagrams do not have all the possible flux lines drawn in. In a scale diagram, the concentric circles would extend much farther from the center. In fact, on the far sides of the pari of wires, flux lines from both would meet once again. These lines, as you may have guessed, would be in opposite directions, and therefore cancel each other out. The result of having an increased magnetic field between them, and a decreased magnetic field on their outsides pushes the two current-carrying wires back out to a more stable position.

This is one of the few cases in electromagnetism where opposites do not attract! When two wires with current in the same direction are moved together, the opposite happens. Flux lines in the middle are in opposite directions, and so cancel out, whereas lines on the outside are increased. The result is that the two wires move even closer.
You may recall from the previous section that magnetic flux lines are also produced by magnets. When a current-carrying wire is placed in a magnetic field, as in the diagram, it too is forced to move.
