Recent microwave experiments demonstrate the anapole-moment and magnetoelectric properties in quasi-2D ferrite particles with magnetic-dipolar-wave oscillating spectra. The theory developed in this paper shows that there are the macroscopically quantum topological effects. Quantum coherence for macroscopic systems refers to circumstances when large numbers of particles can collectively cooperate in a single quantum state. These effects are rarely observed through macroscopic measurements because statistical averaging over many states usually masks all evidence of quantum discreteness. Magnetic-dipolar oscillating modes in normally magnetized ferrite disks demonstrate properties of a Hamiltonian system. The purpose of this paper is to show that because of the adiabatic motion process for such a Hamiltonian system one has macroscopic quantum effects of symmetry breaking, magnetic currents, and eigen electric moments.
