N820

The N820 is a NdFeB Block Magnet usually specified by their three dimensions such that the first two dimensions detail the size of each magnet pole face and the last dimension specifies the distance between the poles (the magnet is magnetised in the same direction as the last dimension). For very tall magnets (where the height is larger than the pole face dimensions, the block magnets are referred to as bar magnets and such magnets have their own online section). The larger the pole face area the better the magnet will be at attracting through larger air gaps (the magnet will project a stronger field at distance). Magnets can be stacked in multiples of their pole to pole distance (they will attract each other to build height) which will give increases in performance but increasing the magnet height further will eventually start to give less and less increase as the performance starts to plateau off.
