In mathematics, the magnitude or size of a mathematical object is a property which determines whether the object is larger or smaller than other objects of the same kind. More formally, an object's magnitude is the displayed result of an ordering (or ranking) of the class of objects to which it belongs.
The following are important identities in vector algebra.Identities that only involve the magnitude of a vector ‖ ‖ and the dot product (scalar product) of two vectors A·B, apply to vectors in any dimension, while identities that use the cross product (vector product) A×B only apply in three dimensions, since the cross product is only defined there.
By a transformation of variables, [14] any central-force problem can be converted into an equivalent parallel-force problem. [ note 6 ] In place of the ordinary x and y Cartesian coordinates, two new position variables ξ = x / y and η = 1/ y are defined, as is a new time coordinate τ τ = ∫ d t y 2 {\displaystyle \tau =\int {\frac {dt}{y ...

is the charge density measured by an inertial observer O who sees the electric current moving at speed u (the magnitude of the 3-velocity); ρ 0 {\displaystyle \rho _{0}} is “the rest charge density”, i.e., the charge density for a comoving observer (an observer moving at the speed u - with respect to the inertial observer O - along with ...
