Earth’s magnetic field is not produced by an internal dynamo within the planet

Experiment SG1016

Blacksmiths use the transformation temp to harden and
temper steels, at this point iron becomes nonmagnetic
now weather it still causes those effects in the
magnetosphere is something I couldn’t answer but
a simple experiment using iron filings, an aluminum plate
and a magnetized bar heated to transformation temp could
possibly provide some answers or at least some more
questions.

Yeah, I only today found out that iron loses it's ability to be magnetisted at high temperatures. I did not know that, but perhaps it can still generate a magnetic field spinning at a high temp? Also the pressures are immense so perhaps high pressure counters high temperature? And lastly there are other metals beside iron in the Earth liquid core maybe they are generating the magnetic field? lol this is not my area of expertise.

One theory is that the “flips” may mirror or be sympathetic to similar “flips” on the sun.

Yeah, I’m just a simple blacksmith of thirty years
experience and not a scientist, it may be the Mass
that creats the current not the magnitism, in any
event there are large amounts of Iron in the earths
mantle that aren’t molton and so they would still
have an effect on the magnetosphere.
As I remember the transformation temp is around 1170 to
1210 F. depending on carbon content, not quite Cherry
red even. At this point the atomic structure of the metal
transforms sic. from a face centered cubic lattice to a
body centered lattice at which point the atoms of carbon
can fit between the iron atoms. When it’s brought to
this point is becomes nonmagnetic although how much so
is a point I don’t know.
Our whole society is built on the ability of steel to
do this little shift. When the metal is cooled rapidly
from an open state to a closed one the carbon atoms
become entrapped leading to a stressed state, this is
hardness, when the metal is slowly reheated to a lower
temp the strain eases and is called tempering so you
loose hardness and gain toughness, up to the transformation
point at which you lose those properties again.
People no longer recognize our society as an Iron Age
but it runs on it everyday.

Note, it could be from face centered to body centered
or vice versa, it’s been a long time since I did my
self study of ferris metalurgy.

I used to experiment with japanese temper lines in knife
and sword blades, using refactory coatings on the backs
and faces of the blades.

Olympus Mons

I should have said too that we'd have to get geologists there for that kind of work. Maybe some day.

Though I still doubt this overall theory.

What is the status of Mercury re molten core and magnetic field?

Thanks for the ping Civ.

Someone (I apologize for not remembering the name of the FReeper) posted a very interesting link the other day....

An electric universe. What do you think?

My pleasure.
