In vector calculus and physics, a vector field is an assignment of a vector to each point in a space, most commonly Euclidean space R n. A vector field on a plane can be visualized as a collection of
The flow field around an airplane is a vector field in R3, here visualized by bubbles that follow the streamlines showing a wingtip vortex.

An electric field is a physical field that surrounds electrically charged particles such as electrons. In classical electromagnetism, the electric field of a single charge describes their capacity to
Vector field
…in Euclidean space, a magnitude and direction for the force experienced by a charged test particle at that point; the resulting vector field is the electric field. A gravitational field generated by any massive object is also a vector field. For example, the gravitational field vectors for a spherically symmetric…
Evidence of an electric field: styrofoam peanuts clinging to a cat's fur due to static electricity. The triboelectric effect causes an electrostatic charge to build up on the fur due to the cat's motions. The electric field of the charge causes polarization of the molecules of the styrofoam due to electrostatic induction, resulting in a slight attraction of the light plastic pieces to the charged fur. This effect is also the cause of static cling in clothes.
