Abstract

Los defectos en los materiales ferromagnéticos se detectan y se caracterizan al analizar los campos magnéticos de los artículos para encontrar porciones de los campos magnéticos que difieran en formas características de los campos magnéticos residuales generados por porciones no defectuosas de los artículos; las porciones de ,os campos magnéticos que difieren de las formas características corresponden a las ubicaciones de los defectos; los campos magnéticos residuales corresponden a las porciones de los artículos distantes de los defectos; la caracterización de los defectos puede incluir volumen de la pérdida del material debido a cada defecto y/o/ profundidad de cada defecto.
