Abstract

UN IMAN PERMANENTE DE ALTA INTENSIDAD DE CAMPO QUE TIENE UNA PLURALIDAD DE CAPAS, EN DONDE AL MENOS DOS DE LAS CAPAS ESTAN FORMADAS DE MATERIALES DE DIFERENTE REMANENCIA. LA REMANENCIA DEL MATERIAL DE CADA CAPA NO ES SUPERIOR A LA DE LAS CAPAS QUE SE ENCUENTRAN POR DEBAJO DE LA MISMA Y ES PREFERENTEMENTE INFERIOR A LA REMANENCIA DE TODAS LAS CAPAS SUBYACENTES. LA CAPA INTERIOR PUEDE ESTAR FORMADA DE UNA ESTRUCTURA MAGNETICA EN QUE TODA O PARTE DE LA CULATA BASICA SE HA SUSTITUIDO POR UNA DERIVACION DE MATERIAL ACTIVO. CADA DERIVACION SE PUEDE UTILIZAR ALTERNATIVAMENTE EN UNA ESTRUCTURA MAGNETICA DE UNA SOLA CAPA.
