一个电磁永动机?
An electromagnetic perpetuum mobile?
摘要:
根据拉莫尔公式,在绕地球的轨道上自由运动的电荷辐射。如果这条路是封闭的,它将构成一个永久移动。这个能量悖论的解决方案在C. M. DeWitt和B. 1964年的德威特本文的要点是在弯曲时空中对辐射电荷的运动方程进行了修正。在本文中,我们解释了这种修改背后的物理学,并使用广义方程来解决永久移动悖论。
英文摘要:
A charge moving freely in orbit around the Earth radiates according to Larmor's formula. If the path is closed, it would constitute a perpetuum mobile. The solution to this energy paradox is found in an article by C. M. DeWitt and B. DeWitt from 1964. The main point is that the equation of motion of a radiating charge is modified in curved spacetime. In the present article we explain the physics behind this modification, and use the generalized equation to solve the perpetuum mobile paradox.
