suppose we do not excite it or depress it, will it perform spin forever?
HallsofIvy said:Really, "spin" (and "iso-spin) is so-called only because it transforms like a classical angular momentum.
jtbell said:I would say that with "spin" the connection is stronger than that, because it's been experimentally established that the "spin" of individual electrons contributes to the total macroscopic angular momentum of an object (e.g. the Einstein - de Haas effect).
Electron spin is a fundamental property of an electron and it does not involve any motion in the traditional sense. It is not considered a form of perpetual motion as it does not involve the continuous motion of matter without an external source of energy.
No, electron spin cannot be harnessed to create perpetual motion machines. While electrons do have a spin, it is a quantum mechanical property and does not involve physical motion that can be harnessed to continuously produce energy without an external source.
The laws of thermodynamics state that energy cannot be created or destroyed, only transformed. Electron spin does not violate these laws as it is a fundamental property of an electron and does not involve the creation or destruction of energy.
Yes, the spin of an electron can change over time, but it does so in a predictable and controllable manner. This change in spin does not involve the creation or destruction of energy and does not violate the laws of thermodynamics.
No, there is currently no practical application of electron spin in perpetual motion. While there is ongoing research on utilizing the spin of electrons in various technologies, it is not possible to create a perpetual motion machine using electron spin.
