1. The problem statement, all variables and given/known data Find the force of attraction between 2 magnetic dipoles a distance r apart. Both dipoles point to the right. 2. Relevant equations 3. The attempt at a solution All I need help with is figuring out how to determine if the force is attractive or repulsive between the 2 dipole moments. From the question, it seems as though I can conclude that 2 magnetic dipoles pointing in the same direction attract each other. But I need a more fundamental way to figure this out. If I'm given 2 dipoles a distance r apart (where r is not huge) and with some orientation (relative to each other), how do I determine whether there is an attractive force or a repulsive force?
