The basic structure of the log rotary disk of this embodiment differs from the two embodiments described above in that the rotary mechanism is a magnetomotive mechanism. The principle of the magnetic mechanism is that when the upper disc is shifted clockwise, the main permanent magnet ring 7 and the auxiliary permanent magnet ring 11 are arranged through the axis connecting line direction without penetrating through the center of the rotating shaft, and the principle of N pole repulsion is utilized, namely the auxiliary permanent magnet ring 11 pushes the upper disc body 1 to rotate by homopolar thrust, so that the rotating time is prolonged.

The upper disc body 1, the vertical shaft 3 and the rotary ring 6 are bonded into a whole to form an outward rotation structure, and the main permanent magnet ring 7 is arranged at an angle close to 30 degrees inclined downwards, so that magnetic force lines are mainly concentrated on the lower disc body 2, and a better health care effect is generated. When the hand is slightly shifted, the upper disc body 1 can maintain long-time rotation by utilizing initial power, rotating inertia force and homopolar repulsive force between the main permanent magnet ring 7 and the auxiliary permanent magnet ring 11. .
