暂者,不久也.本文的暂态过程,指的是事物发展所经过的各个历时极短的阶段.金属杆在匀强磁场中滑行时,由于动生电动势的大小与金属杆的运动状态有关,所以通常会出现暂态过程,研究这类问题时,大多数人只关心过程的始末状态,笔者觉得这样的解答不够圆满.下面就金属杆滑行问题中几 Temporary, and soon also. The transient process of this article refers to the extremely short period of time that the development of things has passed. When the metal rod slides in a uniform magnetic field, the magnitude of the electromotive force is related to the motion of the metal rod. , so usually there will be a transient process, when studying such issues, most people only care about the whole process of the process, the author thinks that such a solution is not satisfactory. The following issues on the metal rod sliding problem
