What is the ratio of force between two parallel currents?
The ratio F/l is the force per unit length between two parallel currents I 1 I 1 and I 2 I 2 separated by a distance r. The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the pinch effect in electric arcs and other plasmas.

What happens when two wires carrying current are parallel to each other?
When two wires carrying a current are placed parallel to each other, their magnetic fields will interact, resulting in a force acting between the wires. The magnitude of the force acting on each wire is equal, but the directions are opposite. This is true even if the conductors carry currents of different magnitudes.
Why do two parallel wires attract?
So if you have two current-carrying, parallel wires with magnetic fields circling around them in the same direction, they will attract each other, as shown in the tutorial; at the point at which their respective magnetic fields intersect, they are traveling in opposite directions, and opposites attract.
Why do two parallel wires repel?
Since the currents would be flowing in opposite directions, the wires will repel each other. This is a consequence of Ampere's law and the Lorentz force law. From Ampere's law you can use the right-hand rule to determine the magnetic field.
