Learn about the concept and definition of magnetic flux density, a vector field that describes the force exerted on charged particles in motion. Find out how to measure and calculate B using the cross product and the Lorentz force law.
In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or Φ B. The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds), and the CGS unit is the maxwell. [1]
The name magnetic flux density and the symbol $B$ are defined by International Bureau of Weights and Measures (BIPM) as one of the coherent derived physical units.
The gauss (symbol: G, sometimes Gs) is a unit of measurement of magnetic induction, also known as magnetic flux density. The unit is part of the Gaussian system of units, which inherited it from the older centimetre–gram–second electromagnetic units (CGS-EMU) system.
Magnetic flux density is defined by the symbol B; It is measured in Tesla (T) Rearranging the equation for magnetic force on a wire, the magnetic flux density is defined by the equation: Where: B = magnetic flux density (T) F = magnetic force on a current-carrying wire (N) I = current (A) L = length of the wire (m) For reference, the Earth's ...
Magnetic flux is given the symbol Φ and is measured in units called Webers (Wb). However the amount of magnetic flux flowing through a given area will change from one point to another around the magnet and you can understand this by thinking about a loop of wire placed in the field at two different points (A and B).
