We know that magnetic field is a non-conservative field, since it exists in closed loops.
Then how can we define the potential energy of a magnetic dipole placed in a magnetic field ?

$\begingroup$ We talk about forces being non conservative, it doesn't matter if the magnetic field has closed loops, firstly it isn't bad force field, secondly the force depends on velocity so the conservative nonconservative doesn't apply. So it's not clear what your problem is with dipoles in magnetic fields. $\endgroup$– TimaeusCommented Aug 17, 2015 at 21:31

$\begingroup$ Where do you get the magnetic field to be non-conservative? $\endgroup$– rmhleoCommented Aug 17, 2015 at 21:46

$\begingroup$ can you please clarify whether the Magnetic field is a conservative or a non-conservative force field ? because I was told that it is a non conservative field.. $\endgroup$– AbhirikshmaCommented Aug 18, 2015 at 0:55
