Noun
(physics) the number of changes in energy flow across a given surface per unit area
Source: WordNetConversely, one can consider the flux the more fundamental quantity and call the vector field the flux density. Source: Internet
It is also possible to combine the electric displacement field D with the magnetic flux density B to get the Minkowski form of the Poynting vector, or use D and H to construct yet another version. Source: Internet
Given a flux according to the second definition, the corresponding flux density, if that term is used, refers to its derivative along the surface that was integrated. Source: Internet
In disagreement to the statement in the previous section, a measurement of the magnetic flux density very close to the magnet is related to by the formula : The effective magnetic dipole can be written as : Where is the volume of the magnet. Source: Internet
In this mode, the amount of thrust generated by a magnetic sail falls off with the square of its distance from the Sun as the flux density of charged particles reduces. Source: Internet
Magnetic flux The magnetic flux density ( magnetic field ) having the unit Wb/m 2 ( Tesla ) is denoted by B, and magnetic flux is defined analogously: : with the same notation above. Source: Internet
