explain how an electric field is produced.
user
an electric field is produced by a charged particle, such as an electron or a proton. in a vacuum, electric fields emanate radially outward or inward from the particle. when the charged particle is in a medium, the electric field will follow the shape of the medium, due to the material's permittivity or its ability to allow the electric field to pass through it. electric fields can also be produced by electric currents, such as those in an electric circuit.
