What is "magnetic flux"

magnetic field \magnetic field\ n. (Physics) The space around a magnet through which it exerts magnetic force; a field of force surrounding a permanent magnet, electrical current, or a moving charged particle; called also magnetic flux and field of magnetic force.

magnetic flux \magnetic flux\ n.

1. A measure of the strength of a magnetic field over a given area.

2. Same as magnetic field.

n. (context physics English) A measure of the strength of a magnetic field in a given area.

1. n. a measure of the strength of a magnetic field over a given area

2. the lines of force surrounding a permanent magnet or a moving charged particle [syn: magnetic field, flux]

In physics, specifically electromagnetism, the magnetic flux (often denoted or ) through a surface is the surface integral of the normal component of the magnetic field B passing through that surface. The SI unit of magnetic flux is the weber (Wb) (in derived units: volt-seconds), and the CGS unit is the maxwell. Magnetic flux is usually measured with a fluxmeter, which contains measuring coils and electronics, that evaluates the change of voltage in the measuring coils to calculate the magnetic flux.
