Operators. 2 The Curl Operator This operator acts on a vector field to produce another vector field. Let be a vector field. Then the expression for the. - ppt download: 3 The physical significance of the curl operator is that it describes the “rotation” or “vorticity” of the field at the point in question. It may be regarded as a measure of how much the field curls around that point. The curl of is defined as an axial ( or rotational) vector whose magnitude is the maximum circulation of per unit area as the area tends to zero and whose direction is the normal direction of the area when the area is oriented so as to make the circulation maximum. where the area is bounded by the curve L, and is the unit vector normal to the surface and is determined using the right – hand rule.
