    Abstract: A balanced magnetic string and methods for forming same are described. The balanced magnetic string includes at least a plurality of magnetic elements linearly arranged in an alternating magnetic polarity pattern and each comprising a first magnetic volume and a compensating magnetic element having a second magnetic volume that is different than the first magnetic volume. The plurality of magnetic elements and the compensating magnetic element magnetically interact to provide a resultant magnetic field having a desired magnetic field strength at a point of interest.
