• ### Difference between Electric flux density,electric field

2011-2-20  In electromagnetism, flux always means total flow through a surface (a scalar), and is measured in webers (magnetic flux) or volt-metres (electric flux). flux density (btw, this is density per area, not per volume) is the same as the field . flux = ∫ field "dot" area, so field = flux per area = flux density .

Permeability, on the other hand, is a measure of how easily a magnetic field can be set up in a material. However, rather than just being a measure of the ratio of the m.m.f. to the flux it produces, permeability takes into account the distribution of the flux within the material. Permeability is the ratio of the flux density of the magnetic ...

Magnetic field meters convert between flux density and field strength by setting internally μ r = 1. This is permissible because the sensor does not measure “inside” the ferromagnetic material, but always outside of the material, hence in air. In air, μ r is approximately 1. From equation (e2) follows: 1mT ^ = 7.96A/cm.

The higher the magnetic susceptibility, the higher the induced field density in the particle and the greater is the attraction up the field gradient toward increasing field strength. Diamagnetic minerals have lower magnetic susceptibility than their surrounding medium and hence expel the lines of force of the external field.

• ### Unit Conversion Table of Magnetic Flux Density

Magnetic field strength is defined by vector field which has a direction and a magnitude (or strength). The relation between Magnetic strength H and flux density B can be defined by B = μH. μ in this case is permeability, the unit of magetizability. In the air, μis usually about 1, except special case, and 1 Gauss ≒ 1 Oersted.
