Аннотация:The equilibrium of a spherical magnetizable body in a magnetic fluid drop resting on a horizontal plane in a uniform horizontal magnetic field is studied experimentally and theoretically. The dependences of the ball levitation height on the volume of the magnetic fluid and on the applied magnetic field are obtained numerically. In contrast to a vertical field in which noticeable levitation of a body has been predicted theoretically and confirmed experimentally, in a horizontal field, the theory predicts only a small lift of the ball, which is confirmed experimentally (levitation of the body has not been observed). The case of a tilted magnetic field is also investigated experimentally. It is found that the ball can levitate not only in a vertical, but also in a tilted magnetic field (in a certain range of tilt angles).
