All magnet were measured in the same orientation.  The magnet is layed flat with the top of magnet is pointed toward the 0 angle of the Helmholtz coil and the label is visable.  The dot is on the bottom surface. The N(orth) magnets should have a 0 angle in the X-Y orientation and the S(outh) magnets should have a 180 degree angle.  The numbered magnets should have an
