The like currents i.e current in both the wire are in the same direction attracts each other . The force is repulsive when current flows in opposite direction through the wires.
`F = (mu_(0) I_(1)I_(2)dl)/(2 pi r) `
i.e `F alpha 1/r`

As wire of loop carrying opposite current is near so the net force acting on the loop is repulsive.
