[0070] How it works

[0071] When the rubidium magnet moves in the copper tube, some unique physical phenomena will occur, mainly including:

[0072] Electromagnetic induction:

[0073] According to Faraday's law of electromagnetic induction, the moving rubidium magnet generates a changing magnetic field in the copper tube, which in turn induces an electric current in the copper tube. This phenomenon can be used to develop electrical energy.

[0074] Damping effect:

[0075] The moving rubidium magnet will encounter resistance from the eddy current generated by the copper tube as it moves in the copper tube. Eddy current is the current induced in the conductor due to the change in magnetic field caused by the movement of the rubidium magnet. This current forms a magnetic field in the copper tube, which has a damping effect on the rubidium magnet. This effect is very important in vibration control and damper design.

[0076] Dynamic Behavior:

[0077] The movement of the rubidium magnet in the copper tube is affected by gravity, friction and electromagnetic force, and its motion equation can be described by Newton's second law. According to the mass, speed and balance of the force of the rubidium magnet, its motion trajectory, acceleration and other dynamic characteristics can be analyzed. Attenuation.

[0078] The role of the disc spring here is:

[0079] Providing resilience:

[0080] When the rubidium magnet is passively or affected by external forces and deviates from its equilibrium position, the disc spring will generate a restoring force to push the rubidium magnet back to its original position. This effect is very important for maintaining the stability of the system.

[0081] Absorb vibration:

[0082] When the neodymium magnet moves in the copper tube, especially when it is subject to external interference or vibration, the disc spring can effectively absorb these vibrations, reduce the impact on the system, and ensure the normal operation of the equipment.

[0083] Enhanced damping effect:

[0084] The elasticity of the disc spring combined with the moving nephelium magnet can produce a damping effect through the electromagnetic induction effect. When the nephelium magnet moves, the elasticity of the disc spring provides additional resistance, thereby enhancing the damping effect of the system and helping to improve the efficiency of vibration control.

[0085] Improve responsiveness:

[0086] The disc spring's design and material properties allow it to respond quickly to the movement of the neodymium magnet, allowing it to quickly adjust the system's state to accommodate varying motion conditions.

[0087] Simplified design and integration:

[0088] The compact design of the disc spring enables it to be effectively integrated with the neodymium magnet and copper tube system, simplifying the overall design and reducing the system size.

[0089] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.
