Electric field - Wikipedia
An electric field (sometimes called E-field [1]) is the physical field that surrounds electrically charged particles. Charged particles exert attractive forces on each other when their charges are opposite, and repulse each other when their charges are the same.
Electric field | Definition, Units, & Facts | Britannica
2024年9月6日 · electric field, an electric property associated with each point in space when charge is present in any form. The magnitude and direction of the electric field are expressed by the value of E, called electric field strength or electric field intensity or simply the electric field.
What Is an Electric Field? Definition, Formula, Example - ThoughtCo
2019年8月28日 · An electric field is a region of space around an electrically charged particle or object in which an electric charge would feel force. An electric field is a vector quantity and can be visualized as arrows going toward or away from charges.
Electric Field: Definition, Properties, Examples & Problems
2023年2月17日 · An electric field is an invisible force field caused by an electric charge. It is an alteration in the space (air or vacuum) around the charge. It results in an electric force that is felt by electric charges when placed close to one another.

5.5: Electric Field - Physics LibreTexts
Fortunately, it is possible to define a quantity, called the electric field, which is independent of the test charge. It only depends on the configuration of the source charges, and once found, allows us to calculate the force on any test charge.
电场 - 百度百科
电场是电荷及变化磁场周围空间里存在的一种特殊物质。 这种物质与通常的实物不同，它虽然不是由分子原子所构成的，但它却是 客观存在 的特殊物质，具有通常物质所具有的力和能量等客观属性。 [1] 电场的力的性质表现为：电场对放入其中的电荷有 作用力，这种力称为 电场力。 电场的能的性质表现为：当电荷在电场中移动时，电场力对电荷做功，说明电场具有能量。 [1] 19世纪30年代,英国科学家法拉第提出了“电荷的周围存在着由它产生的电场”这一观点，随后物理学理 …
18.3 Electric Field - Physics - OpenStax
If you know the electric field, then you can easily calculate the force (magnitude and direction) applied to any electric charge that you place in the field. An electric field is generated by electric charge and tells us the force per unit charge at all locations in space around a charge distribution.
Electric Field - HyperPhysics
Electric Field. Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge. Click on any of the examples above for more ...
