Abstract
EN UN DISPOSITIVO PARA LA VERIFICACION DE OBJETOS DE MEDIDA EQUIPADOS CON PROPIEDADES MAGNETICAS, DONDE UN DETECTOR TIENE UN CIRCULO MAGNETICO CON UNA ESCISION DE AIRE DE AL MENOS UN MATERIAL MAGNETICAMENTE BLANDO O MAGNETICAMENTE PERMANENTE, DONDE PREVALECE EL CIRCULO MAGNETICO DEL CAMPO ESTATICO GENERADO MEDIANTE EL MATERIAL MAGNETICO PERMANENTE. PREFERIBLEMENTE, LA ESCISIÑON DEL AIRE SE FORMA ENTRE UN EXTREMO DEL MATERIAL MAGNETICAMENTE BLANDO Y UN POLO DEL MATERIAL MAGNETICAMENTE PERMANENTE.
