A vector field is a mathematical concept used in physics and engineering to describe a mapping of vectors (quantities with both magnitude and direction) to points in space. Each point in the space is associated with a vector, which typically represents some physical quantity such as velocity, force, or electromagnetic field strength. Vector fields are often visualized using arrows, with the direction of the arrow indicating the direction of the vector and the length of the arrow representing the magnitude of the vector at that point.
Purpose :
