Electrostatics - Wikipedia
Electrostatics is a branch of physics that studies slow-moving or stationary electric charges. Since classical times, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, ἤλεκτρον (ḗlektron), was thus the …
静电场 - 百度百科
静电场，指的是观察者与电荷量不随时间发生变化的电荷相对静止时所观察到的电场。 它是电荷周围空间存在的一种特殊形态的物质，其基本特征是对置于其中的静止电荷有力的作用，库仑定律描述了这个力。
What is electrostatic field? – TechTarget Definition
What is an electrostatic field? When two objects in each other's vicinity have different electrical charges, an electrostatic field exists between them. An electrostatic field also forms around any single object that is electrically charged with respect to its environment.
Electric field - Wikipedia
The study of electric fields created by stationary charges is called electrostatics. Faraday's law describes the relationship between a time-varying magnetic field and the electric field.

We develop a trick that allows us to discuss forces and fields that result from bringing free charges near flat plane conductors. We begin with a study of electric fields due to static charge distributions.
Electrostatics | Definition & Formulas | Britannica
2024年11月14日 · electrostatics, the study of electromagnetic phenomena that occur when there are no moving charges—i.e., after a static equilibrium has been established. Charges reach their equilibrium positions rapidly, because the electric force is extremely strong.
4 Electrostatics - The Feynman Lectures on Physics
The electric field in electrostatics is an example of a curl-free field. You can practice your vector calculus by proving that $\FLPcurl{\FLPE}$ is zero in a different way—by computing the components of $\FLPcurl{\FLPE}$ for the field of a point charge, as given by Eq.
Gauss’s Law is a powerful method to find the electric field of certain charge distributions when we can take advantages of symmetry. Field inside a uniformly charged solid sphere
