Question

Can anyone explain the difference between the B magnetic field and the H one?

Answer 1

The H is the magnitude of the magnetic field, and the B is the so called induction. H is the magnetic FIELD density, and B the magnetic FLUX density.

Answer 2

Materials such as iron are good conductors of magnetic flux, so the magnetic flux density is higher within the conductor than in the free space around it. H the magnetic field intensity gives an idea of the magnetic influence due to a source regardless of the medium.
\[H=B/\mu\]
where \[\mu\] is \[\mu _{o}\mu _{r}\] the permeability of free space multiplied by the relative permeability.

Answer 3

ok...lets see ...
There are 2 kinds of magnetic fields
inside and outside magnetic force
B=measured in teslas
H=ampere-turn
in a vacuum they are indistinguishable
inside a material they are distinguishable

obviously there are other types d, h, b but as an example.....here it is..
