Hi everyone!
My knowledge of physics is very very basic, so I just found this great forum and I think it would be great to have a feedback from people who know.
I am in development of a project that involves a laptop sleeve and some magnets. I've already done my research and found that they doesn't really affect functioning of laptops unless they are really, really strong.
All over the internet, the answer is the same: neodymium magnets are the best choice. They are strong, light and come in many thicknesses, which seems to fit my needs. But here comes my questions:
1) How much does the thickness of the magnet affects the strenght of it? A lot? Not even too much to care? The idea is to attach things to the sleeve and, if wanted, carry it in a bagpack without concern of things falling from the sleeve.
2) Is there any way to isolate one of the "faces" (polarities) of a rounded neodymium magnet so it won't even "touch" the laptop? I mean a light and very very thin solution, like a coating or something if posible.
3) What happen if I put a lot of them across the sleeve in, let's say, squared enclosures? Are they going to start atracting one another? Is there a minimun distance I should keep between them?.
4) Are neodymium magnets "water resistant"? They will rust if the sleeve is washed by hand?
5) As I said, my knowledge is pretty basic, but I am really excited about learning. Any suggestion is widely welcome.
I am not sure if this is the correct section to post this thread, if is not, I would be pleased to be notified where I can post it.
Thanks a lot in advance. I am really pleased to find spaces like this one around the internet.
