F=(μ0/4 π)((6 M M'/d4)) in end-on position.

Q. Two small bar magnets are placed in a line with like poles facing each other at a certain distance $d$ apart. If the length of each magnet is negligible as compared to $d$ , the force between them will be inversely proportional to

$d$

$d^{2}$

$\frac{1}{d ^{2}}$

$d^{4}$

$F = \frac{μ _{0}}{4 π} (\frac{6 M M ^{'}}{d ^{4}})$ in end-on position.
