Abstract

configurações de ímãs. um arranjo de ímãs é revelado, compreendendo uma pluralidade de ímãs poliédricos dispostos em uma configuração cilíndrica de halbach, os centros dos elementos individuais da pluralidade de ímãs poliédricos sendo substancialmente dispostos em um plano de uma estante magnética, a pluralidade de ímãs poliédricos encerrando, pelo menos parcialmente, um volume de teste e compreendendo uma primeira pluralidade de ímãs poliédricos dispostos em uma configuração cilíndrica de halbach, e uma segunda pluralidade de ímãs poliédricos dispostos em uma configuração não-halbach. em outro aspecto, um arranjo de ímãs é divulgado compreendendo um primeiro e um segundo subconjuntos de ímãs poliédricos com diferentes coercividades. ainda em outro aspecto, um arranjo de ímãs é divulgado, em que um subconjunto dos centros dos elementos individuais de ímãs poliédricos é deslocado lateralmente de uma posição nominal na estante de ímãs para neutralizar um gradiente de campo magnético do arranjo de ímãs.
