In this review, we shall call any gravitationally-bounded object having an angular momentum and intrinsic magnetic field by the term ``gravimagnetic rotator'' or simply, rotator. In order to specify the intrinsic properties of the rotator, three parameters are sufficient - the mass M, the total angular momentum (I is the moment of inertia and is the angular velocity), and the magnetic dipole moment (see Figure 3). Given the rotator radius , one can express the magnetic field strength at the poles by using the dipole moment . The angle between the angular moment and the magnetic dipole moment can also be of importance: .
