Abstract

EL CAMPO MAGNETICO TERRESTRE DE UN TUBO DE IMAGEN SE COMPENSA CON LA AYUDA DE UNA BOBINA COLOCADA EN EL. PARA LA BOBINA SON NECESARIAS CORRIENTES DE DIFERENTE DIRECCION E INTENSIDAD. LO CORRIENTE ES UN DISPOSITIVO CON DOS INTERRUPTORES COLOCADO EN LA PARTE POSTERIOR DEL APARATO. CON UNA DE LOS INTERRUPTORES PUEDE MODIFICARSE LA DIRECCION DE LA CORRIENTE, CON EL OTRO LA INTENSIDAD. EL MANEJO ES COMPLICADO Y LA INTENSIDAD DE LA CORRIENTE SOLO PUEDE CAMBIARSE EN DOS PASOS. LA TENSION (VS) PARA LA ALIMENTACION DE LA BOBINA DE COMPENSACION (5) SE PRODUCE A TRAVES DE UN CANAL DE MANDO A DISTANCIA DEL APARATO. COMPENSACION DEL CAMPO MAGNETICO TERRESTRE.
