Halbach Array

thingiverse

This is a straightforward base for assembling multiple magnets to create a Halbach array, which essentially cancels out the magnetic field on one side while intensifying it on the other. I opted for simple, compact rare earth bar magnets measuring 15x6.5x3 from Amazon and paired two at a time with glue to form squares that could fit snugly into the holder. To fill the holder completely, each square must be rotated so its north pole faces towards the top (12:00 position), then the right side (3:00 position), followed by the bottom (6:00 position), and finally the left side (9:00 position). Once all squares are properly aligned, they can be securely fastened in place.
