In the mathematics of vector calculus, a solenoidal vector field is also known as a divergence-free vector field, an incompressible vector field, or a transverse vector field. It is a type of transverse vector field v with divergence equal to zero at all of the points in the field, that is ∇ · v = 0. It can be said that the field has no ...Divergence at (1,1,-0.2) will give zero. As the divergence is zero, field is solenoidal. Alternate/Shortcut: Without calculation, we can easily choose option “0, solenoidal”, as by theory when the divergence is zero, the vector is solenoidal. “0, solenoidal” is the only one which is satisfying this condition.A solenoidal vector field is a vector field in which its divergence is zero, i.e., ∇. v = 0. V is the solenoidal vector field and ∇ represents the divergence operator. These mathematical conditions indicate that the net amount of fluid flowing into any given space is equal to the amount of fluid flowing out of it. The coil geometry also has effects on transmission efficiency. Solenoidal coil, flat (or spiral) coil, square coil, and circular coil have different efficiency according to the literature [81-83]. The flat coil is widely used in the MRC WPT system.

It was originally introduced by Alexandre Chorin in 1967 as an efficient means of solving the incompressible Navier-Stokes equations.The key advantage of the projection method is that the computations of the velocity and the pressure fields are decoupled.The solenoidal coil can, in principle, be accessed in the transverse direction via the gaps of size L / (N − 1) in between adjacent circular windings, and the spherical coil can also be accessed in the transverse direction in between the circular current loops, which are spaced at equal intervals of d = 2 R / N along its z-axis (see Fig. 4).for a solenoidal field. The above can be easily proven by using the vector identity introduced in the previous section. Therefore, One example of a solenoidal field is a static magnetic field. The field lines do not emanate from or converge to any point, and thus the divergence is zero (), and thus where A is a vector potential.Subscribe to his free Masterclasses at Youtube & discussions at Telegram SanfoundryClasses .
