Default Basic magnetic phenomena explained

Hi all,
Hardly anyone understands magnetism.
For those inclined to read more, you could do well to read up at

http://www.ndt-ed.org/EducationResou.../Magnetism.htm

There is application of ideas to MPI, magnetic particle inspection of
many things to detect cracks
or metal faults.
But basics about magnetics is well explained along with units used.

** The various Wikis on magnetism and electromagnetism are rather more
informative and have better diagrams.

The first dude to ever wind some copper wire around an iron nail was really
onto something....

Maybe that first dude needed to to know a bit about several things
before realizing he was onto anything. Just winding wire around a nail
is a fencing job, or cheap DIY repair.
But if the FD had insulated wire, and a battery, he'd have been a
scientific dude because when he lived, nobody had anything electrical,
( except for a few rich *******s in the royal court in Vienna
where Mozart recorded his music. But that's another separate issue
apart from mainstram dudes, MDs, of 1825 who were mainly exceedingly
dumb brootes, Dbs.) Hardly anyone had any wire, let alone copper wire,
and nails were mainly with a square shank, also very expensive, so the
FD achieved a first wire wrap connection without knowing why.

I reckon RDH4 isn't too bad on the basics about F, B and H, but then
they have R, reluctance, and a load line for the iron and air gap and
NOBODY knows how to interpret that.

So all a man can do is plonk a few turns around a core, measure
current and voltage, view all stuff on CRO, and conclude what
hysteresis must be occurring and what it means in PRACTICAL terms
rather than in scientific lingo which sounds worse than Julia & Tony
on just about anything. Then wennya stick in a gap, you see the
changes in current, and again wennya add DC flow as well. There's SFA
anywhere on the Net were all such observations are made and shown
because the Internet is the Land of the Lazy where ppl babble re-
gurgitated jargon at each other without ever having to make a good
tranny or choke. I'm lucky I have a few other books besides RDH4.

Anyway, I read web-pages of mine I wrote 6 years ago and methinks they
needed more clarity so I re-visited the study of basics and will
repost what I hope are better pages soon on choke designs. Over the
years the formatting of pages gets very messy as well. Must be mice
wandering around inside the data centres, nice and warm in there,
voltages are not too high.

RDH4 has a formula for relating Afe on a core to VA, A = sq.root VA /
5.58. Therefore VA = 31.13 x A squared, A in square inches.
Interesting because in most old books which wrote about most old iron
that existed when RDH4 was written in 1953 have A = sq.root VA / 4.44,
so VA = 19.1 x A squared. There is rather a lot they don't mention
about aspect ratios of T:S plus lots of other stuff. Many old power
trannies were designed using the basic 4.44 constant, and had they
been designed using 5.6 they'd have run far too hot.

Bill Sturgeon, an apprentice shoemaker from Lancashire did it first.

He used bare copper wire, a bent piece of iron and a single cell.

To my knowledge, Mozart never recorded jack **** - there was nothing to
do it with in the late 1700s. If you mean by "recording" that he wrote it out
on staff paper with a pen, sure.

** Mozart pre-dated even the player piano by about 100 years.

That said, his phenomenal popularity suggests that had iPods been available
in 1780, young Wolfgang " tinkling the ivories" would been top of the pops
with all the damsels of the day.

Just like " boy bands " are now ...

They did, however, have "music box"-like instruments
of several varieties, including plucked strings, tines,
and even organs...but they were driven by metal drums
with projections on them, and the music had to be
hardware programmed by the dudes who built them.
Not at all a recording, but a type of primitive mechanical
reproduction.

As far as damsels went, young Wolfgang was reputed
to have been quite successful. Quite. ;-)

Phil, have you forgotten to take your meds lately?

There's a special light blue pill that enables your sense of humerator
to function.

Of course, maybe you've been taking too many brown pills.

Well of course Jack **** wasn't ever going to get recorded. He had a
terrible voice, and couldn't sing in tune like so many other dull
bland and poor cousins and unkels in the Mozart family. Young
"Moatzie" had influential friends who were geniuses like himself, so
they did DIY electricity etc, etc, and they had a little recording
studio with digital effects in the backroom of a wealthy idiot Prince
of Vienna, with more dough than sense. But outside this little "in"
grope, nobody ever found out that they were up to, so 30 years passed
without anyone knowing anything much different, and mean while some
Sturgeon fella was farnarkling around with primitive batteries, copper
wire, and nails and stuff, doing it the hard way. After "Moatzie"
karked it at 35, there were umpteen European wars and revolutions, and
the palace where "little room of tricks" was burnt to the ground, and
the dudes who did the early recording gear lost lives after joining
armies because they wandered around paddocks so absentmindedly trying
to think up a better computer.

History is so unkind and unforgivable.

I never intended to be serious about the matter. Let me know if ya
feel any effects from the pale blue humerator pill. Perhaps they have
zero effect on you, and you will forever remain a grumpy old
curmudgeon. Beware the dark blue pill. That one gives you a hard-on
for a weak, and a hard-on is a device invented, of course, by the
Devil, and, in your hands, it would be a waste if nobody smiled while
ya use it.

Let's see...someone calls you on a matter of historical accuracy.

Your response is to start blathering away about his dick.
