helicidad
- One of them is magnetic helicity, the magnetic analogue of the kinetic helicity (equation 1).
Examples
-
The counterclockwise rotation of the flagella causes them to move in a coordinated bundle according to their left-handed helicity, and the result is a run (Wang et al. 2008).

Moreover, the magnetic analog of kinetic helicity is particularly important for the study of twisted magnetic fields in plasma physics and tokamak fusion.

Topological techniques based on crossing numbers and helicity provide estimates of the amount of energy stored in the magnetic field.

Academic text (1996) -
By direct measurements of helicity and application of conservation of topology, one can estimate average geometric quantities, such as the mean twist of field lines, and their contribution to the total energy.

Since helicity and flux tube strength are measurable conserved quantities, equation 2 provides useful information about the topology of the flow field.

Helicity and topological estimates, together with detailed knowledge of reconnections, can prove to be very useful for the characterization and classification of the most fundamental fluid mechanisms.
Academic text (1996) -
Considerations of helicity and linking numbers, for example, demonstrate that internal rearrangement of magnetic field geometry leads to a spectrum of different asymptotic end-states with the same topology.

Etymology
Helicity comes from the Greek root helix, which means 'spiral' or 'twist'. So, helicity is the quality of being twisted into a spiral, like a corkscrew or the DNA helix, and that is why scientists use it for spiral shapes in physics and chemistry.
