Arrays of permanent magnets are an attractive approach to designing magnets for low field MRI systems as they are affordable, easy to handle and offer great flexibility in magnet designs. However, translating designs from simulations to realised systems is challenging. The difference between the two is often attributed to imperfections in the individual magnets that make up the permanent magnet array. Here we show that non-random errors in the magnet rotations due to imperfect magnet holders can be the dominant cause of this discrepancy and if the imperfections are known they can easily be corrected for during manufacturing.
