WebFlux is the amount of “something” (electric field, bananas, whatever you want) passing through a surface. The total flux depends on strength of the field, the size of the surface it passes through, and their orientation. Your … Webgeometry is often chosen to suit a particular measurement. One striking example is the Flux ball [25] whose complex construction made it possible to perform point measurements in inhomogeneous fields. Measurements are performed either by using fixed coils in a dynamic magnetic field, or by moving the coils in a static field.
