Ufopolitics, how are permanent magnets made? Your textbook is very inaccurate.

Rakarsky,


Want a debate?...sorry, but do not have the time, nor the interest.


You and I know perfectly well "how PM are made"...different thing from what the text book is citing, which is a TEMPORARY FERROMAGNETIC CORE, that when that circular current STOPS FLOWING, the Field collapses.


And so, my point was simple...there are not "Two Magnetic Fields" there...or one for the coil current flowing PLUS "another one" for the core...that is entirely B.S.


Permanent Magnets are made of specific materials, (from ceramics to Neodymium) which happen to have specific characteristics VERY DIFFERENT from a plain and common steel core, whether laminated or not...these characteristics allow them to preserve the Magnetic Field that was "STAMPED" for very long periods of time....some call it "Magnetic Memory"...

Math and scientific theories exist to explain an effect.

I focus on the effect first.

Ufopolitics, Controversy!?

Why is the demagnetization property important for electrical steel? Small magnetic memory?

There are ferro materials that are poorly demagnetized, and if they are poorly demagnetized, then they have their own magnetic field after removing the electromagnetic source that generated the field in the material. Or this field was already there, and this effect is called residual magnetization, it's just that in certain paramagnets it is very high.

The question of the dimensionality of self-induction of a coil with a core and without a core from a ferro material is generally a classic. 

I do not exclude your vision of the problem at all. But I will not concede my point of view.
With respect.

We all live in a huge Magnetic Field...some live closer to the pole division lines...or the middle...or the poles itself...therefore, we are observing all kind that some call "magnetic anomalies" which is a product of our own planet environmental properties.


Fact is that by just spinning a piece of a non magnetized steel bar in a Lathe, at high RPM's...and working on it by just shaving some metal off...it becomes "magnetized"...and we all can see how the shavings keep adhered to the piece of originally "non magnetized steel"... 


There are "Field Effects" everywhere you look around...


Related to the "demagnetization rates" or the "Magnetic Reminiscences"...have a lot to do with the type of Field that "influenced" them...


For example, a constant one way field, being applied to the same piece of steel...for long periods of time, end up magnetizing that piece of steel, even if currents are no longer flowing...BUT NOT with the same intensity as the original field strength!!...yes, it is called "reminiscence"...and we see it in every Generator Rotor Steel Core...which have a "one way" DC Field at all times during operation.


Now, you apply the REVERSE FIELD (reversing current flow), to that same piece of steel...and vualá...it looses all "reminiscence"...


If you are applying a constantly reversing field to a piece of steel...it will hardly get magnetized, or have any magnetic reminiscence...like a Stator in a Generator...
