"And you were right. It does not increase, but concentrate the field to a narrow space. Increasing flux density into a narrower space like using a lens to focus sunlight so you can burn ants."

"The energy in the light does not increase, but is narrowed to a smaller point so the energy density increase."

                                                             Correct


The total sunlight energy, or magnetic flux, appears to increase, but it doesn't. Only the density changes on the expence of a smaller space. "

Quote from  http://hyperphysics.phy-astr.gsu.edu/Hbase/magnetic/elemag.html

"Electromagnets are usually in the form of iron core solenoids. The ferromagnetic property of the iron core causes the internal magnetic domains of the iron to line up with THE SMALLER DRIVING MAGNETIC FIELD produced by the current in the solenoid. The effect is the multiplication of the magnetic field by factors of tens to even thousands."

What do you think this means?

OK I'll bite, What do you think it means ?

Ok:
The magnetism from the coil will align the magnetic polarity of the atoms in the iron in the same direction. This will increase the magnetic flux density through the core. This magnetic flux that exits the iron core is still attracting the iron, so the flux density is very much focused in the close vicinity of the iron, and want to take the shortest path back in to the south pole of the iron core.


This will cause the flux density to be very strong at the poles, tens, maybe hundereds times stronger. However, this increased magnetic flux density have its price. The flux doesn't reach as far any more, because they are to busy with the iron core.


The two iron plates is the reason why closet door magnets are so strong, but doesn't shut the closet door when it is too open. The magnetic flux is virtually jumping directly to the other iron plate on the other side of the magnet, making the closet door magnet weak on distance but very strong when the door is closed, and keep it there until a strong force opens the door, but the door does not even have to move a millimeter before you can open the door with ease.


The conclusion is that the flux density increase with the iron core, but the total available magnetism does not increase. Just focused. You can test this by using two air core coils, and power them up, and then face equal poles close to eachother. The magnetic field is escaping the gap between the coils as a very dense magnetic flux without an iron core, but the total available magnetism hasn't changed a bit.

The goal of this topic is the presentation of replications of the measurement process / experiment.

I do not agree with your interpretations of the information at http://hyperphysics.phy-astr.gsu.edu/Hbase/magnetic/elemag.html .   

Also I do not find your choice of wording to be concise enough to allow for a meaningful response
on my part.

except that

I do not agree with your conclusions.
