Magnetic flux

Magnetic flux is a measure of the magnetic field lines passing through a surface, such as a loop of wire.[1] The magnetic flux through a closed surface such as a sphere is always zero, because the magnetic field lines going into the closed surface are balanced by field lines coming out.[2]

It is the alignment of electrons in the atomic shells of ferromagnets and the “spinning” electrons in electromagnets, that provides a material with it’s magnetism.[3]

The SI unit of magnetic flux is the Weber (Wb; in derived units, volt-seconds). The CGS unit is the Maxwell.

Magnetic flux is sometimes used by electrical engineers designing systems with electromagnets or designing dynamos. Physicists designing particle accelerators also calculate magnetic flux.

  • Magnetic field
  • James Clerk Maxwell demonstrated that electric and magnetic forces are two complementary aspects of electromagnetism.
  • Maxwell's equations describe the behavior of both the electric and magnetic fields, as well as their interactions with matter.
  • Gauss's law gives the relation between the electric flux flowing out a closed surface and the electric charge enclosed in the surface.
  • Magnetic circuit is a method using an analogy with electric circuits to calculate the flux of complex systems of magnetic components.
  • Magnetic mono pole is a hypothetical particle that may be loosely described as "a magnet with only one pole".
  • Magnetic flux quantum is the quantum of magnetic flux passing through a superconductor.
  • Carl Friedrich Gauss developed a collaboration with Wilhelm Eduard Weber which led to new knowledge in the field of magnetism.
