Ive had a look through the forums regarding this subject but I've found more questions than answers to issues that i would like to know
firstly I am planning on building a perminant magnet hoverboard that floats on a perminant magnet floor
slightly crazy i know
the board is a skateboard in size I've covered it in holes 10mm dia 5 mm deep with a 6 hole pcd of 13mm so they are very closely packed together I've done this with a cnc mill so they are pretty accuratly spaced I am planning on doing the same with the floor was going to use a full sheet of ply as a starter
Now for some questions i know Earnshaws theorem won't allow a stable floating magnet in a stable field etc
but if the field is wide enough ie an ice rink i wouldn't slip out of the field as there are walls around the edge of the rink? Is that true would it work? Also issue with board flipping because of size of magnets been used approx 400 on a board would it flip because there isn't enough energy to flip board because there force only exerts over a small range individualy about 250g over about 10mm repulsively
so if boards can't flip because of range of the repulsive force even if it did the amount of force on the other side if the board is reduced due to the thickness of the board
and the board can't leave the field because there are walls around the rink
Would it work? Or would fields combine amoung small magnets etc
i haven't been able to find any info on fields in magnetic arrays and i don't really want to spend a huge anount on magnets just to find out that that there are other forces at work that I am unaware of
im hoping that 400 ish magnets each with 250g of lift will be enough to elivate a person 10mm and not flip the board and the walls around the rink will stop the board leaving the field
the floor will be same spacing and same magnets as board
