Displacement Apparatus on Disturbance of Magnetic Moments
The ferrite magnet is heated by the halogen, and the orientation of spins direction is disturbed, and the demagnetization happens, and then the repulsion to gravity is reduced, and the height is lowered, and the boundary conditions of a string change, and the entire vibration suffers the effects, and then the vibration of the monocode changes. This device, which produces a height of about 5 mm variation in 60 minutes, affects the entire vibration system by making the subtle displacement a change in the boundary condition of one string, and manifests it as a change in vibration.
フェライト磁石がハロゲンにより熱せられ、スピンの向きが乱れ、その結果減磁し、重力への反発が減り、高さが低くなり、弦の境界条件が変化し、振動系全体へ影響し、モノコードの振動が変化する。60分で5mm程度の高低差しか生じないこの装置では、その微小な変位を1本の弦の境界条件の変化にすることで、振動系全体に影響を与え、振動の変化として顕在化させる。
