法拉第冰桶实验是英国科学家麦可·法拉第在1843年进行的一项简单的静电学实验，以演示导电容器上的静电感应现象。这个容器，法拉第用的是一个装冰的铁桶，实验因而得名。实验表明，一导电壳体内封入的电荷会在壳上感应出等量电荷，并且在导体中，电荷全部驻留在表面上。它还演示了电磁屏蔽的原理，这在法拉第笼中也有应用。冰桶实验是第一个对静电荷的精确的定量实验。今天在讲座演示和物理实验课中，该实验仍用以讲解静电原理。

Faraday's ice pail experiment is a simple electrostatics experiment performed in 1843 by British scientist Michael Faraday that demonstrates the effect of electrostatic induction on a conducting container. For a container, Faraday used a metal pail made to hold ice, which gave the experiment its name. The experiment shows that an electric charge enclosed inside a conducting shell induces an equal charge on the shell, and that in an electrically conducting body, the charge resides entirely on the surface. It also demonstrates the principles behind electromagnetic shielding such as employed in the Faraday cage. The ice pail experiment was the first precise quantitative experiment on electrostatic charge. It is still used today in lecture demonstrations and physics laboratory courses to teach the principles of electrostatics.
