Hi Luc.

Great job you're doing, imho

For the problem of sticking the magnets inside safely. What about to glue them of a piece of wood each one separately and to make a guiding system which will guide them in their place between the 2 plates? A long press to force them in the space while having put glue on them first. (I better to try without first to check if it fits well and then to do it again with the glue).

What do you think?

Hi poynt

thanks for your post.

The term Bloch wall, I thought it meant the Neutral point between two magnetic poles and that's what I was using the word as.
If that is not correct, then I have no problem calling it the Poles Neutral Zone if that's a better way to describe it.

In the illustration of the solenoid magnetic field you posted, we can see -> arrows going in different directions. Do these arrows represent a pole direction?

I assume the the fine black rectangle line is the outside of the solenoid coil?... is that correct?

Luc

You are correct Luc... according to wiki...


"A Bloch wall is a narrow transition region at the boundary between magnetic domains, over which the magnetization changes from its value in one domain to that in the next, named after the physicist Felix Bloch.

Bloch walls exist inside solid ferromagnetic material and typically exhibit a 180 degree rotation of the magnetic domains inside this material. An unmagnetized (random) piece of iron will have many Bloch walls inside, some at 180 and some at 90 degrees.

When you have an energized cored coil (such as the one shown in Luc's video), the core is polarized in one direction only, so no Bloch wall exists there. Bloch walls do not exist in air or copper.

Hi all,

Maybe all that you are discussing is what Howard Johnson demostrated by experimental tests in his book "The Secret World of Magnets". He states, and measured with a Hall probe, that the lines of force do not move from one pole to the other but they move from one pole to the center point, forming a double vortex.

Please see the attached picture from his book.
