Abstract
DISPOSITIVO PARA LA DETECCION Y MEDICION DE CAMPOS MAGNETICOS, DONDE EL NUCLEO DEL DISPOSITIVO ES UNA PIEZA DE MATERIAL CON MAGNETORRESISTENCIA ANISOTROPICA (CIRCULO SOMBREADO EN LA FIGURA), A LA QUE SE CONECTAN CUATRO CONTACTOS QUE SE DISPONEN FORMANDO UNA CRUZ (ETIQUETADOS EN LA FIGURA CON LAS LETRAS A, B, C Y D). LOS CONTACTOS A Y C ESTAN CONECTADOS A UNA FUENTE DE INTENSIDAD ELECTRICA Y ENTRE LOS CONTACTOS B Y D SE DETECTA LA CAIDA DE POTENCIAL ELECTRICO, MAGNITUD DIRECTAMENTE RELACIONADA CON EL CAMPO APLICADO SOBRE LA MUESTRA. LOS DETECTORES DE CAMPOS MAGNETICOS TIENEN UN AMPLIO RANGO DE APLICACIONES QUE VAN DESDE LA PROPIA MEDIDA DEL CAMPO MAGNETICO, HASTA SU USO COMO ELEMENTO SENSOR EN LAS CABEZAS DE LECTURA DE LOS EQUIPOS DE GRABACION Y ALMACENAJE DE INFORMACION EN SOPORTE MAGNETICO.
