WebWe can write curl(F~) = r F~. Fields of zero curl are called irrotational. 1 The curl of the vector eld [x 2+ y5;z2;x2 + z] is [ 2z; 2x; 5y4]. If you place a \paddle wheel" pointing into the direction v, its rotation speed F~~v. The direction in which the wheel turns fastest, is the direction of curl(F~). The angular velocity is the magnitude ... WebDivergence is a scalar, that is, a single number, while curl is itself a vector. The magnitude of the curl measures how much the fluid is swirling, the direction indicates the axis around which it tends to swirl. These ideas are somewhat subtle in practice, and are beyond the scope of this course.

WebDec 31, 2024 · The curl can be visualized as the infinitesimal rotation in a vector field. Natural way to think of a curl of curl is to think of the infinitesimal rotation in that rotation itself. Just as a second derivative describes the rate of rate of change, so the curl of curl describes the way the rotation rotates at each point in space.
