Magnetic Flux

== Magnetic Flux ==
By: Jason Osborne

Reviewed By: Will Griffith & Wesley Brown

Magnetic Flux is the measure of the strength of a magnetic field over a given area. <ref>http://www.google.com/search?hl=en&safe=off&client=firefox-a&rls=org.mozilla:en-US:official&hs=lBE&defl=en&q=define:magnetic+flux&ei=gsNKS7r4EYuqsgPdmMT_Bg&sa=X&oi=glossary_definition&ct=title&ved=0CAcQkAE</ref>The Greek letter used to represent flux is Φ, phi. The SI unit for magnetic flux is the Weber. The area used must be perpendicular to the
travel of[[Image:Magnetic_flux.png|right|thumb|300px|Figure 1: '''Magnetic Flux''']] the magnetic lines. The flux can then be determined by how many magnetic lines go
through the area surface. The net flux is the number of magnetic lines going through the area surface in one direction minus the number magnetic lines going through the surface area in the opposite direction. The general quantitative expression for finding magnetic flux is:

:<math>\Phi_m = \int \!\!\!\! \int_S \mathbf{B} \cdot d\mathbf A</math>
where
:'''B''' is the magnetic field
:'''A''' is the surface area<ref>http://en.wikipedia.org/wiki/Magnetic_flux</ref>
If specific situations arise and more variables are known the calculations for magnetic flux can become relatively simple. There are many ways to determine magnetic flux from a variety of equations.
