Solenoidal.

Un solenoide es solo una bobina de alambre, pero cuando pasa una corriente a través de él, se convierte en un electroimán. Las cargas estacionarias producen campos eléctricos, pero las cargas en movimiento producen campos magnéticos. Esto nos permite crear un electroimán haciendo pasar una corriente a través de un cable.A silicon-chip-based 3D metal solenoidal transformer is proposed and developed to achieve AC-DC conversion for integrated power supply applications.

1,675. Solenoidal means divergence-free. Irrotational means the same as Conservative, which means the vector field is the gradient of a scalar field. The term 'Rotational Vector Field is hardly ever used. But if one wished to use it, it would simply mean a vector field that is non-conservative, ie not the gradient of any scalar field.

Solenoidal circulations comprise a broad class of thermally direct atmospheric flows (in which warm air rises and cold air sinks) forced by baroclinity, (R / p) ∇ p × ∇ T ≠ 0. They may range in horizontal scale from that of the atmosphere's general circulation to highly localized ( L ∼ 1–10 km) circulations confined to the PBL.
