Computational fluid dynamics | Numerical differential equations
Flux limiters are used in high resolution schemes – numerical schemes used to solve problems in science and engineering, particularly fluid dynamics, described by partial differential equations (PDEs). They are used in high resolution schemes, such as the MUSCL scheme, to avoid the spurious oscillations (wiggles) that would otherwise occur with high order spatial discretization schemes due to shocks, discontinuities or sharp changes in the solution domain. Use of flux limiters, together with an appropriate high resolution scheme, make the solutions total variation diminishing (TVD). Note that flux limiters are also referred to as slope limiters because they both have the same mathematical form, and both have the effect of limiting the solution gradient near shocks or discontinuities. In general, the term flux limiter is used when the limiter acts on system fluxes, and slope limiter is used when the limiter acts on system states (like pressure, velocity etc.). (Wikipedia).

Flux Integrals | Lecture 42 | Vector Calculus for Engineers
A flux integral is the surface integral of a vector field. For examples, the mass flux is computed in fluid mechanics and the electric and magnetic fluxes are computed in electromagnetism. Both types of flux integrals are discussed in this video.

Magnetic flux density measured for beginners: from fizzics.org
The strength of a magnetic field or the flux density can be measured using a simple balance to measure the force produced by a known opposing field. The video demonstrates this measurement using simple equipment and follows through with a calculation of the answer. Notes on measuring magne
