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.

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.
28 sie 2019 · 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.
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.
17 lut 2023 · 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. A static electric field is created when the charges are stationary, and the corresponding force is known as electrostatic force.
The units of electric field are newtons per coulomb (N/C). If the electric field is known, then the electrostatic force on any charge \(q\) is simply obtained by multiplying charge times electric field, or \(\mathbf{F}=q\mathbf{E}\). Consider the electric field due to a point charge \(Q\).
Originally intended as merely an "explanation" of action-at-a-distance, the idea of an electric field turns out to be a much more useful model than one might expect. 1.3: Computing Electric Fields for Known Charge Distributions.
