Web15.1: Vector Fields. Vector fields are an important tool for describing many physical concepts, such as gravitation and electromagnetism, which affect the behavior of objects over a large region of a plane or of space. They are also useful for dealing with large-scale behavior such as atmospheric storms or deep-sea ocean currents. WebExample 1. Use the curl of F =< x 2 y, 2 x y z, x y 2 > to determine whether the vector field is conservative. Solution. When the curl of a vector field is equal to zero, we can … WebConversely, we can calculate the line integral of vector field F along the boundary of surface S by translating to a double integral of the curl of F over S.
