An electric field (sometimes called E-field [1]) is a physical field that surrounds electrically charged particles. In classical electromagnetism, the electric field of a single charge (or group of charges) describes their capacity to exert attractive or repulsive forces on another charged object.

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.

2025年1月30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.

2025年1月15日 · 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.)

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.

An Electric field can be considered an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. Electric fields are usually caused by varying magnetic fields or electric charges.

2024年5月10日 · Electric field lines are imaginary lines used to depict the direction and strength of an electric field surrounding charged objects. They were introduced by the physicist Michael Faraday in the 19th century as a conceptual tool for understanding electric fields.

2016年2月14日 · An electric field is defined as the region surrounding an electrically charged object. Within this field, any other charged objects will experience an electromagnetic force. Electric field strength, also known as electric field intensity, measures the magnitude of this field.

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 ...

2024年5月27日 · Explore the basics, effects, and applications of electric fields, from electronics to medical imaging, and their role in daily life and technology. An electric field is a fundamental concept in physics, representing the area around an electric charge that experiences a …
