Solenoidal.

The inductance, L, is defined in terms of the current, I, flowing through the system, and Wm, the magnetic energy density is proportional to B2. The magnetic field, B, exists within and outside of the wire. Within the wire, it increases linearly outwards from the centerline, and outside of the wire it falls off as 1/ r, where r is the radius.It is clear from Fig. 32 that if we take a closed surface containing an isolated magnetic pole, which is usually termed a magnetic monopole, then : the flux will be positive for an isolated South pole, and negative for an isolated North pole. It follows from Gauss' theorem that if then . Thus, the statement that magnetic fields are solenoidal ...solenoid: [noun] a coil of wire usually in cylindrical form that when carrying a current acts like a magnet so that a movable core is drawn into the coil when a current flows and that is used especially as a switch or control for a mechanical device (such as a valve).SOLENOIDAL AND IRROTATIONAL FIELDS The with null divergence is called solenoidal, and the field with null-curl is called irrotational field. The divergence of the curl of any vector field A must be zero, i.e. ∇· (∇×A)=0 Which shows that a solenoidal field can be expressed in terms of the curl of another vector field or that a curly field ...

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.

In particular, deep convection is often initiated along the leading edge of evaporatively chilled thunderstorm outflows, which are sometimes referred to as 'gust fronts'. Gust fronts are often evident as fine lines of weak ...Function. The solenoid structure's most obvious function is to help package the DNA so that it is small enough to fit into the nucleus. This is a big task as the nucleus of a mammalian cell has a diameter of approximately 6 µm, whilst the DNA in one human cell would stretch to just over 2 metres long if it were unwound. [6]

What are irrotational field and solenoidal field? A Solenoidal vector field is known as an incompressible vector field of which divergence is zero. Hence, a solenoidal vector field is called a divergence-free vector field. On the other hand, an Irrotational vector field implies that the value of Curl at any point of the vector field is zero.
