Electric field - Wikipedia
网页The electric field (lines with arrows) of a charge (+) induces surface charges (red and blue areas) on metal objects due to electrostatic induction. Electromagnetic fields are electric and magnetic fields, which may change with time, for instance when charges are in motion.
Electric Field: Definition, Properties, Examples & Problems
网页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.
Electric field | Definition, Units, & Facts | Britannica
网页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
网页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.
5.5: Electric Field - Physics LibreTexts
网页The electric field, then, is the mechanism by which the electric properties of the source charge are transmitted to and through the rest of the universe. (Again, the range of the electric force is infinite.)
18.3 Electric Field - Physics - OpenStax
网页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.
