The neutral center is the point of dispersion or redistribution of each of the two bar magnets. Polarized activity is repelled or pushed away from this center of high harmonicity. Like and unlike poles do not repel each other. The neutral center of each combine and moves to the center of them both when joined. Seeming repulsion is a result of differentiation of/in sympathy, ala Bjerknes Effect. The poles, when the magnetic is doubled, migrate to the ends demonstrating magnetism is not an attribute of the iron but is an attribute of magnetic flow proper.
