If you have a weak magnetic field out here, the flux is going to be lower than if you have a strong magnetic field. That's analogous to, when you had high density and high velocity, that was a lot of flux. Versus low density or low velocity that is lower flux. And also, we can increase the total surface.

WebGauss's law for magnetism, which is one of the four Maxwell's equations, states that the total magnetic flux through a closed surface is equal to zero. (A "closed surface" is a surface that completely encloses a volume (s) with no holes.) This law is a consequence of the empirical observation that magnetic monopoles have never been found.
