Here is where I wish I had a laboratory where I have both type I and
type II superconductors and
various different superconductors of those types and where I perform
both the Meissner Effect
and the Oersted Effect. The Oersted Effect is where you take a compass
needle to the
superconductor and it is deflected perpendicular to the current flow.

Researchers the world over have conducted numerous Meissner Effects,
but sadly none of
them have ever conducted a Oersted Effect.

Theoreticians have come up with this idea of "Vortices" to reconcile
the diminution of the
Meissner Effect in type II superconductors.

But here I would ask them a question, since none have performed the
Oersted Effect.
Ask them why does type I perform the same Oersted Effect as type II??
Now honestly
I am guessing that is the result, because, obviously I do not have a
laboratory of those
cold superconductors to run that test.

Obviously there is a diminishing of the Meissner Effect from type I to
type II, but if there
is no diminishing of the Oersted Effect from type I to type II, then
this Vortices Concept
is rubbish as an explanation.

Logically, if Type I and Type II have the same Oersted Effect
indicates that it is Temperature
that affects the difference in the Meissner Effect.

Looking at Poole's "Handbook of Superconductivity" 2000, on pages 553
to 558 where a
discussion of Vortices, I tried to locate how that discussion is
really a masquerade discussion
of the Oersted Effect.

Keep in mind that the Vortice Concept was deviced to reconcile the
weaking Meissner Effect
in type II. But, if the Oersted Effect remains constant when going
from Type I to Type II, then
one has to logically question that Vortices have nothing to do with
Meissner Effect and that
the reason the Meissner Effect is waning is because of increased
temperature and temperature
is not vortices.

So I was looking at the mathematics of Poole's Handbook on
Superconductivity to see if that
vortices math is nothing more than a disguised Oersted Effect
mathematics.

--- quoting Poole's Handbook of Superconductivity, page 554 ---
Ordinarily, vortices arrange themselves in the hexadic pattern of Fig.
12.6 separated by the
distance d, where 1/2sqrt3xd^2 is the area occupied per vortex.
--- end quoting ---

To me that looks awfully similar to just merely the Maxwell Equation
of magnetic field gradient
that gives the Oersted Effect.

So, in other words, vortices have nothing to do with why the Meissner
Effect wanes from
type I to type II, and because the Oersted Effect does not wane from
type I to type II
leaves us only with Temperature as the cause of the waning of the
Meissner Effect.

And we all know that heat affects magnetic properties.
