动生电动势电荷量
**Electromotive Force Generated by Motion and Charge Quantity** When a conductor moves within a magnetic field, an electromotive force (EMF) is induced within it. This phenomenon, known as motional electromotive force, arises due to the interaction between the moving charges in the conductor and the magnetic field. The EMF is proportional to the rate of change of magnetic flux linkage with the conductor and is given by Faraday's Law of Electromagnetic Induction.
电荷量，通常表示为Q，是描述电荷多少的物理量。

在国际单位制（SI）中，电荷量的单位是库仑（C）。

电荷可以是正电荷或负电荷，分别代表着失去或获得电子的带电粒子。

在电路中，电荷的移动形成了电流，而电流的大小与电荷量、移动的速度以及导体的电阻都有关系。

The charge quantity, denoted as Q, is a measure of the amount of charge present. In the International System of Units (SI), the unit of charge quantity is the coulomb (C). Charges can be either positive or negative, depending on whether they have lost or gained electrons. In an electrical circuit, the movement of charges gives rise to a current. The magnitude of this current depends on the charge quantity, the speed of its movement, and the resistance of the conductor.
