I mad a ferrophoto of my last upload of the 2 bar magnet with the steel bar between them . Both poles are facing the same ways. I used window light to show the ferrophoto.
Candle lit version showing 3d ness of the Ferrophoto magnet field imprint
showing that weak magnets are usable on a ferrocell and are much more controllable than strong magnets. Notice how the internal fields move towards and away from each other.
This is the same Ferrophoto of the 4 bar magnets I made a video of last time. This time I use the red and blue flash lights.
Ignore what I say in the video. I don't think that the fields of the 4 magnets are attracting. I'm forcing 4 magnets together with similar poles up. The corners do appear to be in the centre of the magnets the closer they are to the ferrocell. this config is basically acting as one magnet.
when the magnets get close to each other you can still see separate fields.
Ignore the circles seen between the magnets they are burned in patches from some disk magnets and are not caused by the magnets fields.
The ring magnet is under the ferrocell and the stack of disk magnets is on top of the ferrocell. A bit of visual fluff.
Move along kid not much to see here .
