when u will look at the MO diagram of boron nitride , then
boron have 3 valence electron and nitrogen have 5 valence electron this makes 8 electron ,
u have to start filling from the orbitals with lowest energy
so, 2 electron is sigma (2s) , and 2 electron is sigma star(2s) , 2 electron in sigma ( 2p )
u have 2 electron left and 2 orbitals of same energy .,
now , u have to follow hunds rule , and after that when u filled u will end up with 2 unpair electron ,
so, paramagnetism nature is explained .
