Electric field
Electric Field
The Electric Field (pronounced: /ɪˈlɛktrɪk ˈfiːld/) is a fundamental concept in the field of Electromagnetism. It is a vector field that associates to each point in space the Coulomb force that would be experienced per unit of electric charge, by an infinitesimal test charge at that point.
Etymology
The term "Electric Field" was first coined in the 19th century by British scientist Michael Faraday. The word "electric" comes from the Greek word "ēlektron" which means amber, a material that can generate static electricity when rubbed. The word "field" in physics refers to a region in space where a particle experiences a force.
Definition
The electric field is defined mathematically as a vector field in space that quantifies the electromagnetic force per unit of charge experienced at any point in space. It is represented by the symbol E.
