The magnetic interaction is described in terms of a vector field, where each point in space is associated with a vector that determines what force a moving charge would experience at that point (see Lorentz force). … See more

For example, a change in the magnetic flux passing through a loop of conductive wire will cause an electromotive force (emf), and therefore an electric current, in the loop. The … See more

Gauss'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 … See more

While the magnetic flux through a closed surface is always zero, the magnetic flux through an open surface need not be zero and is an important quantity in electromagnetism. See more

By way of contrast, Gauss's law for electric fields, another of Maxwell's equations, is
$${\displaystyle \Phi _{E}=\,\!}$$ $${\displaystyle \scriptstyle S}$$
