[General] Foundational questions Tension field stable particles

Let's begin with your question at the end.

It is a good and a challenging question in so far as we treat magnetism 
in our everyday live in a way which does not reflect the true physics 
behind it. Normally if we have to do it with magnetism, then it is a 
magnetic dipole. And when we measure a magnetic field we use another 
magnetic dipole, i.e. we measure the force or the angular momentum onto 
this test dipole.

The clean way to measure a magnetic field is to use an electric test 
charge. If there is a force acting on the test charge we have to check 
whether this force can be explained by the presence of another charge 
using the Coulomb law. Then we have to build the difference between the 
force given by the Coulomb law and the real force observed. This 
difference is "magnetism".

If we say that the earth has a magnetic field, we mean that it is a 
magnetic dipole. And we measure the field strength by the use of another 
magnetic dipole, we may call the latter one a "test-dipole".

Now your question regarding the Earth. To measure the magnetic field of 
the Earth physically, one should use an electrical test charge and 
measure the force on it. Now, if the earth is not electrically charged, 
the result will be 0. That means no magnetic field is detected. Should 
now the observer move together with his charge in relation to the Earch, 
there will be a force. That means during his motion he will see a 
magnetic field. - This answers your question how it can be achieved that 
an observer does not see a magnetic field. Normally he will not see it 
anyway. Our daily experience is of course different. Because if someone 
starts to measure the magnetism of the earth he will use a dipole as 
said above; with the conclusion that there is a magnetic field. And it 
will be extremely difficult (I think impossible) to move a dipole so 
that it will not see a magnetic field. The reason is simple. In a 
magnetic dipole, which is generally a coil with a current in it, there 
are always charges at some position in the coil which are in a motion 
state to the moving charges in the Earth, so one will register magnetism.

You mention a "magnetic body". I do not feel that this is a good way to 
name it. The magnetic body at the end is an electric charge. And that 
one is only "magnetic" if it is viewed from a certain perspective.

Then you say: A propagating EM wave has oscillating E and B vectors. A 
dipole oscillation induces oscillating E, which generates its own 
restoring force B, ...   Please have in mind that this is the 
understanding of Maxwell's theory. But Maxwell is good for the practical 
use of electromagnetism, but it does not reflect the cause of magnetism.

If you have general doubts about my description of magnetism I should 
say that all this is not my idea but main stream physics, can be found 
in textbooks e.g. about SR. However ignored by most practising main 
stream physicists.
