Two long conductors, separated by a distance d carry current $I_{1}$ and $I_{2}$ in the same direction. They exert a force F on each other. Now the current in one of them is increased to two times and its directions is reversed. The distance is also increased to 3 d. The new value of the force between them is

$F \propto \frac{i_{1} i_{2}}{a}$ Since one of the current increase two times

and distance increases three times, so force become $\frac{2}{3}$ times. Also due to the reversal of direction of current force becomes negative.

The exact formula for the magnetic force per unit length between two parallel current-carrying conductors:

$\frac{F}{l} = \frac{?_{0} I 1 I 2}{2 ? d}$ For more information, check: Force between parallel conductors
