The diagram shows two ways to periodically arrange N identical permanent bar magnets. The magnetic moments of the magnets are all parallel in configuration 1. The moments are alternately parallel and anti-parallel in configuration 2.

Choose a finite volume V that encloses almost all the magnetic flux produced by either configuration. Which configuration has the larger total magnetic energy in V and why?
