Will NdFeB magnets be mutually exclusive?

yes, as long as it is a magnetic material, it is divided into N/S poles, so the two magnetic steels must repel each other in the same direction and attract each other in different directions. I don't know what your magnetic steel structure is like. If it is a simple two-stage magnetizing, then the attraction and repulsion may be equivalent; But if it is point magnetizing or radial magnetizing, I dare not say, it is a bit complicated, mainly depending on your structure and magnetizing direction.
