- I have two identical powerful disk-like magnets (with hole in the center). They have same size. They are stuck together (attract).
- I have a bunch of sphere magnets. I left them "collide" and form a blob. So, their magnetic field align freely.
- Same for cubic magnets - they are stacked in a line (50cm).
- What happen if close to a magnet I put a piece of iron (same size/shape)?
Will the magnets demagnetize?
What is the best way to store them as close as possible. I don't afford to put one magnet in each corner of the room, because I don't have enough corners :)
If I have to keep them together, when do they demagnetize faster? When they have same polarity (reject each-other, N-N) or when they are left to "choose" their position (N-S)?
Update: to simplify the question: can I store all magnets in a box? what if some of them also contain iron shell/chasing (like magnets from speakers)?
I googled this, but every single website has its own idea/explanation on this. Seems that magnetism is very poorly understood.
My feeling is that a magnet will not demagnetize if its filed is "flowing naturally". If you place a similar magnet in opposite direction to it (repelling), their magnetic field will conflict and they will get demagnetized. If you place the same magnets so that they attract, they will not demagnetize.
