I wonder whether the current in a single wire will attract each other?
Eventually shrink to a line?

The answer is no. Current in a wire is simply the flow of electrons, and electrons have negative charges. Opposite charges attract each other, so the current in the wire will actually repel each other.
When current flows through a wire, it creates a circular magnetic field around the wire. This is due to the movement of the electrons, which have a magnetic moment, causing them to align and create a magnetic field.
Yes, the strength of the magnetic field is affected by the material of the wire. Materials with higher electrical conductivity, such as copper, will produce a stronger magnetic field compared to materials with lower conductivity.
Yes, the magnetic field created by the current in a wire can attract or repel other objects, depending on their magnetic properties. For example, if a wire with current flows near a magnet, it can either attract or repel the magnet depending on the direction of the current.
Changing the direction of the current in a wire will also change the direction of its magnetic field. For example, if the current flows clockwise, the magnetic field will also be in a clockwise direction. Reversing the direction of the current will result in the magnetic field also being reversed.
