Solenoidal field.

This follows from the de Rham cohomology group of $\mathbb{R}^3$ being trivial in the second dimension (i.e., every vector field with divergence zero is the curl of another vector field). What is special about $\mathbb{R}^3$ which allows this is that it is contractible to a point, so there are no obstructions to there being such a vector field.Example 2 The u velocity component of a steady, two-dimensional, incompressible flow field is uax bxy=−2, where a and b are constants. Velocity component v is unknown. Generate an expression for v as a function of x and y.Consider an i nfinitesimal fluid elements a s shown in Fig. 1 -3, which represents the flow field domain based on Cartesian, cylindrical and spherical coordinate respectively. The term κThe U.S. Department of Energy's Office of Scientific and Technical InformationDue to the well-known bell-like curve shape of the solenoidal field, the integration step has to include the field maximum. Practically, it means that to be consistent with the traditional matrix the integration interval Δ z has to include the whole effective magnetic field length L , beyond which the field is assumed as null, yielding Δ z = L .

A second explanatory theory is discussed in which radiation from the cloud tops of the “intertropical convergence zone” locally reverses the equatorial solenoidal field to produce two new lines of convergence, one on each side of the equator.

As an example, we analyze the composition of external forces that do no work and reaction forces of nonintegrable constraints in the model of a nonholonomic Chaplygin sphere on a plane. We prove that, when a solenoidal field is applied, the general mechanical energy, the ...But a solenoidal field, besides having a zero divergence, also has the additional connotation of having non-zero curl (i.e., rotational component). Otherwise, if an incompressible flow also has a curl of zero, so that it is also irrotational, then the velocity field is actually Laplacian.

More things to try: vector algebraExplanation: For a solenoidal field, the divergence will be zero. By divergence theorem, the surface integral of D and the volume integral of Div(D) is same. So as the Div(D) is zero for a solenoidal field, the surface integral of D is also zero. The magnetic field on the axis of a circular current loop (Eq. 5.41) is far from uniform (it falls off sharply with increasing z). You can produce a more nearly uniform field by using two such loops a distance d apart (Fig. 5.59).
