Thought the eggheads would like this one. Sorry my
physics is fuzzy, and I shouldnt care but do...
However the debate goes on, these authors state;
"leakage flux is a essential aspect of the ideal
transformer".
They have to rationalize how a transformer can work
without flux lines crossing the cores...
When I went to school B and H were strictly defined
when talking about effects. B is defined as a cross
section of amp/turns per area of cross section: H was
the magnetic intensity per unit length of core...
>From records...
Around the early 80's I also attended Akron State Univ
after dropping out, but the different text from that
same Elementary Classical Physics course does not seem
to deal with H at all, as the other text did. In the
early 90's I purchased another Physics text,(Physics
for Scientists and Engineers) in which the following
is noted on pg 654;
We have named B the magnetic field and H the magnetic
intensity. These names are not universal. Sometimes B
is called the magnetic flux density and H is called
the magnetic field. Admittedly, the terminology is
confusing, and universal adoption of a single set of
terminology is unlikely in the near future.
Fortunately, the usage of the symbols B and H as we
have defined them is nearly universal. Thus the
calculation of a magnetic force on a moving charge or
a current nearly always involves B; similarly H is the
appropriate field in Ampere's Law.
Of course the above authours deal with H, and never
mention B, so I see every explanation can be made
according to the authours viewpoint. according to how
they wish to explain effects...
