There is a big difference.
Every object responds to the gravitational field in exactly the
same way, since the force is proportional to the mass of the
object and therefore the acceleration is independent of the
mass. That is why gravity can be modeled as curved spacetime.
This is definitely not the case with electric and magnetic forces.


Two Kg of magnets exerts twice the force of one Kg of magenets.
Same as gravity.


This is true, but one cannot state that 1 kg of magnet will exert the
same force on a 1 kg piece of plastic 1 meter away as on a 1 kg piece of
iron.


I didn't say a gravitational mass would be equal to a magnetic
mass.


However, the Earth exerts the same force in both cases.


No... look at the earths magnetosphere. It is not isotropic.

I didn't say it was a good idea. But it certainly isn't
out of GR's domain.

With respect to the world line of a given observer, the
electromagnetic field tensor decomposes into two vectors,
the electric and magnetic field vectors (3 components each).

You would be better off to say "a two gauss magnet exerts twice the force of
a one gauss magnet" as I can have two magnets of identical masses that have
much different field strengths.

I can also combine two magnets into a system that has very little external
magnetic field or into a system that has twice the field of either magnet
alone.

I especially want to make the point that for a given material
that you don't double the force without also doubling the
gravitational mass. A ferrite loopstick is 0 gauss but you
can't hollow it out to lighten it without also spreading out
it flux lines and making it unsuitable for you pocket AM
radio.

We could probably post the question to
s.p.r and find out if it is a fair 2D version of GR's curvature
or concentration of energy density. Chris Hillman's article
linked in this thread, leads me to believe it is but I am not
getting out of the wading pool just to play a drowning scene.

I guess you have never magnitized something.

The magnetic force goes from zero to some specific number of gauss without
any[measurable] change in the mass of the object.

And that is after the current flow through the coil is turned off.

Just increase the tuning capacitor to bring it back into resonance.

It appears they might be:
At risk of getting my ankles wet:



"How does matter couple to space-time so
that space-time becomes curved?"
The Weyl tensor turns out to be analogous in many
ways to the electromagnetic field tensor, which you
can think of as an antisymmetric four by four matrix
(6 algebraically independent components at each event).
With respect to the world line of a given observer, the
electromagnetic field tensor decomposes into two vectors,
the electric and magnetic field vectors (3 components each).
--C. Hillman
http://www.physlink.com/Education/AskExperts/ae98.cfm

The elegance of these equations [EFT]stems from the
simple replacing of partial with covariant derivatives,
a practice sometimes referred to in the parlance of GR
as 'replacing partial with covariant derivatives'. These
equations are sometimes referred to as the curved space
Maxwell equations. Again, the second equation implies
charge conservation (in curved spacetime)

Obviously!?

However, pretty surely you are, but sure, you never would be, for the simple
reason, that, it is the geometry itself, that it curves everything along the
needs all along, a definitely as a matter a fact.
