Based on recent measurements of the scattering length of spin-changing collisions, it was established that the ground state of optically trapped 87Rb spinor Bose condensates is ferromagnetic. The present study shows that this result, combined with the recent experimental realization of regular arrays of Bose-Einstein condensates in optical lattices, leads to a situation where it becomes possible to carry out detailed static and dynamic studies of magnetism on one- to three-dimensional periodic lattices. It is shown that spinor condensates undergo a ferromagneticlike phase transition that leads to a "macroscopic" magnetization of the condensate array.
