electric field
noun
- a field of force surrounding a charged particle within which another charged particle experiences a force Compare magnetic field
electric field
- The distribution in space of the strength and direction of forces that would be exerted on an electric charge at any point in that space. Electric fields themselves result directly from other electric charges or from changing magnetic fields. The strength of an electric field at a given point in space near an electrically charged object is proportional to the amount of charge on the object, and inversely proportional to the distance between the point and the object.

Example Sentences
These devices can take many forms, such as a collection of superconducting circuits, or a lattice of atoms or ions held in place by lasers or electric fields.
Unlike electrons, ions move due to both electric fields and diffusion, and the researchers determined that their movements at pore intersections are different from what was described in Kirchhoff's law.
Caterpillars respond defensively to electric fields similar to those emitted by their natural predators, scientists at the University of Bristol have found.
This property is polarization, the direction -- left or right -- that electric fields take as they move around a photon.
According to current industry standards, a material is considered to have very good electromechanical performance if it can undergo a 1% change in shape -- or strain -- in response to an electric field.
