helicity picâri Fr.: hélicité 1) In particle physics, the projection of the spin of an elementary particle
on the direction of momentum. |

kinetic helicity picari-ye jonbeši Fr.: hélicité cinétique In fluid mechanics, a quantity that describes helical flow. It is
defined by the integrated scalar product of the velocity field and the

magnetic helicity picâri-ye meqnâtisi Fr.: hélicité magnétique A quantity that measures the extent to which the magnetic field lines
wrap and coil around each other. It is closely related to field line topology.
Magnetic helicity is defined by:
A is the vector potential of the magnetic field
and the integration is over a volume V.
