Neodymium magnets

We need- Neodymium magnets with strongest force on the top of the north pole and almost zero pulling force on the south pole?
Or..maybe if is possible to produce rare earth magnets with ONLY ONE POLE-NORTH POLE?
Following your answer we will provide my purchase request and that will depend of your answer.
If is possible to produce rare earth(strongest) magnets only with north pole (or at least with very weak-almost zero pulling force of SOUTH pole) than we will be interesting to purchase large orders!!
Of course than we will send you drawings for the shape and measurements for the requested purchase of N52 magnets with above mentioned property`s!!
