Get Price #### Difference Between Magnetic Field and Magnetic Flux

Oct 07, 2015· The magnetic field strength (the magnetic flux density) can be defined using the force felt by a particle of charge travelling through it at a velocity :. If the magnetic field is perpendicular to the direction of particle's motion, then we have, If the term "magnetic field" is used to refer to a quantity rather than a region, it is most likely referring to the magnetic field strength.

The Magnetic Field Intensity or Magnetic Field Strength is a ratio of the MMF needed to create a certain Flux Density (B) within a particular material per unit length of that material. c. Its unit. H = At/m, ampereturns per meter. Often, N is used as the number of turns of wire around a core or magnetic material.

Example Electric Field Strength. The voltage between two plates is 230 V and the distance between them is 5 mm. The electric field strength can be calculated as. E = (230 V) / ((5 mm) (103 m/mm)) = 46000 volts/m = 46 kV/m. Electric Flux Density. Electric flux density is the ratio between the charge of the capacitor and the surface area of ...

The permeability of material changes with the amount of magnetic flux forced through it. The specific relationship of force to flux (field intensity H to flux density B) is graphed in a form called the normal magnetization curve. It is possible to apply so much magnetic field force to a ferromagnetic material that no more flux can be crammed ...
