This type of interaction, though, is impossible because the two 1s electrons simultaneously terminate one revolution and, thus, their respective magnetic fields offset each other. The second possibility would be the situation that the 2s electron “notices” and somehow “couples” the self-interaction of a 1s electron, e.g. in direction 1 (see Fig. 4), with its own self-interaction. This would be true if the period of revolution of the 1s and 2s electrons were identical due to the magnetic field theorem. As this is not the case, “disturbances” do not occur here. But let’s stick to the idea that the self-interaction of one electron could be “coupled” with the self-interaction of another electron. This would be the case if the two electrons would not belong to the same nucleus. As we have to demand both electrons to have the same revolution period, i.e. the two electrons have to coincide with respect to their principal (and certainly also secondary) quantum numbers, this could possibly be the explanation for a pure homopolar compound, e.g. for a H₂ molecule?. But as we know from quantum theory, this requires an anti-parallel spin-setting as a precondition. Indeed, we have to be prepared for this, as well, because the H₂ molecule has reduced its contribution to the external interaction in the case of two anti-parallel spin rosettes , i.e. the H₂ molecule is more similar to an inert gas than the single atom. Hence, the electron “prefers” the “undisturbed” self-interaction or the “slightly disturbed” or coupled self-interaction to the external interaction. How does such a “coupling” look like if the spin rosettes are anti-parallel to each other? The same will happen that has previously been discussed for superconduction: both electrons revolve in the same sense of revolution around direction 1! Thus, for the coupled self-interaction we obtain a result that is contrary to Lenz’s induction law: coupled self-interaction will generate a force of attraction only if the sense of revolution and the revolution period around the space direction , in which the coupling exists, are identical for the two partners. We should have to expect this result because otherwise the self-interaction could not exist under these conditions. And this is just the same result as provided by quantum theory: If the spins of the partners are arranged parallel to each other, a repulsive force will be generated. So, we can write down the following theorem:
