Interesting position as well, Smoky.


About measurements, one common measurement error is this: people fully charge a Cap, then use it for a brief moment, then calculate the energy consumed by looking at the caps voltage drop, then they say like:
only 0.1V drop from 100.1 to 100.0 vdc, that equals (assuming a 1 farad cap):
1 * ((0.1 * 0.1) /2) = 0.005 joule
But that is totally wrong. What you need to calculate is:
(1*((100.1*100.1)/2)) - (1*((100*100)/2)), equals 10.005 joule.
It makes a huge diffrence whether you drop 0.1v at 100v, or at 1v.
I add this here because this cap measurement method is often used in conjunction with magnetic devices.

@dieter


  no worries... your not off topic.... especially when you return to how
                   it relates to the magnetic component
         
  Nice
           thanks and appreciateion for your perspectives.

Thanks, Floor.


Another interesting observation I wasn't aware of, that I saw in a FEMM simulation, is, assuming FEMM is correct, when you place an iron shield in front of your magnet, the maximum field density that was at the Bloch wall has moved right into the iron bar, which is practicly stealing the field density from the PM.


If you place two PMs N vs S with a gap and in rhe gap the end of an iron bar, in 90deg angle, that' a bit thinner than the gap, both PMs will try to link with the ironbar, but one will eventually win. Depending on which one, the polarity of the iron bar will be swapped. And according to FEMM the iron bar will hold the highest field density.


Now consider we have a setup in which the gap is only 1mm... what enormous field density we have in there, and by moving the iron bar, or rigid sheet by only 0.5mm, well have complete polarity reversal in the iron bar. Although this requires the iron bar contact area to be saturated by one magnet.


Hmm, I got to test this in FEMM.


Yet another interesting observation: two PMs, N vs S, can use the Bloch wall of a third magnet to link their flux, in 90deg to the third magnet. I have no idea why the magnetic domains at the Bloch wall don't react to these forces.

Ok so you take a large magnet and a 2 small magnets
Put a small one forced opposite to the large
And glue or tape it there so it doesn't fly away
You may have to leave a little gap to get it just right
Depends on the two different magnets
Now when you approach this arrangement with the
Remaining small magnet, there are 3 field encounters
1) the small magnets field
2) the large magnets field
3) the cumulative field formed by the two occupying the
     same space.


By changing their physical orientation you can control how
The two individual fields affect the cumulative field, in such a
way that the warping caused by the approaching small magnet
Causes the cumulative field to change drastically.
This drastic change is like a spring releasing, because the two
magnets (or more) are forced to sit in a way that the cumulative
field is right on the edge of the drastic change. Just a tiny bit more
forcing and the cumulative field reorients itself.


By "explosion" I analogize the effect of a magnetic field change to
the order of tens to thousands of times.
Much more than the required forcing that caused the change.
When the smaller magnet is pulled out (or allowed to repel out)
The cumulative field reverts back to its "springy" state before you
caused the change.


Magnetically speaking, it explodes. (and resets)
The cumulative field will always morph to the gradient
of least resistance.
