• ### Flu Density And Field Strength Relationship

Mar 17, 2016· This was done for each pole. The magnetic field for the South Pole was initially measured to be -32 gauss at 0.5cm, and the final measurement at 3.5cm was -6 gauss. As the distance away from the magnetic field increased, the strength of magnetic field decreased (but in the negative direction). This is consistent with the expected outcome.

So for ferromagnetic materials the ratio of flux density to field strength ( B/H ) is not constant but varies with flux density. However, for air cored coils or any non-magnetic medium core such as woods or plastics, this ratio can be considered as a constant and this constant is known as μ o, the permeability of free space, ( μ o = 4.π.10-7 H/m ).
