Problem C16:
In the figure below there are two wires, each of **finite length**
√ n_{2}d.
Each wire carries a current I. The wires are parallel to each other and
are separated by a distance n_{1}d. What is the net magnetic force that
one finite wire exerts on the other finite wire? That is, if the
net magnetic force that one finite wire feels due to the other is
F = n_{3} (μ_{0} I^{2})/π , what is n_{3}?
Note that n_{1}, n_{2}, and n_{3} are unitless.
