Electric dipole in a magnetic field: some aspects of the problem

In the paper some regimes of motion of an electric dipole placed in a uniform magnetic field are considered. The motion of both three-dimensional and two-dimensional dipole in the plane perpendicular to the magnetic field is studied. In the case of a two-dimensional dipole is discussed, in particular, the regime of chaotic dipole motion, which arises when, along with the magnetic field, there is an electric field rotating in the plane of motion. The motion of a three-dimensional dipole is discussed in cases that allow for analytical consideration. Finally, the same examples are used to discuss the quantum-mechanical approach to the problem.
