Abstract:
Multipole magnet arrays have the potential to achieve greater forces than homogeneous magnets for linear spring applications. This paper investigates the effects of varying key parameters of linear multipole magnet arrays in relation to their force bearing potential. Equal sized arrays in repulsive configurations are vertically displaced to each other; only vertical forces are compared. The force versus displacement characteristic is dependent on the aspect ratio of the arrays, the wavelength of magnetisation, and the total number of magnets used in the array. Some general design guidelines for optimising the repulsive forces are established based on the results.
