[Getdp] vector normal to a magnet

using the examples « Rotating electric machines » from OneLab, I try to
build a model for this permanent magnet electrical machine :



In the file pmsm.pro from OneLab, one imposes a radial Br on the magnet


  // For a radial remanent b

  For k In {1:nbMagnets}

    br[ Rotor_Magnet~{k} ] = (-1)^(k-1) * b_remanent * Vector[
Cos[Atan2[Y[],X[]]], Sin[Atan2[Y[],X[]]], 0 ];



How do I construct a vector normal to the magnets ?


Thanks for any help,
