Magnetic Flux

Magnetic Flux

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 area used must be perpendicular to the travel of 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.
