Abstract
Procedimiento para compensar los campos magnéticos parásitos, especialmente en un avión, con el fin de permitir medir con precisión la intensidad del campo magnético exterior, especialmente el campo magnético terrestre y sus perturbaciones, caracterizado por el hecho de que consiste en generar una primera tensión proporcional, con un primer coeficiente de proporcionalidad, a la intensidad del campo magnético total en un primer punto situado a una primera distancia del baricentro de los campos magnéticos perturbadores, en generar una segunda tensión proporcional, a la diferencia entre las intensidades de los campos magnéticos totales en este primer punto y en un segundo punto situado a una segunda distancia de dicho baricentro, el multiplicar dicha segunda tensión por un factor fi función de dicha primera distancia generando una tercera tensión proporcional , con dicho primer coeficiente de proporcionalidad, a la intensidad del campo magnético perturbador en dicho primer punto, en sustraer esta tercera tensión de la primera tensión obteniendo una cuarta tensión y en determinar la amplitud de esta cuazrta tensión, que es proporcional a la intensidad del campo magnético exterior a medir en dicho primer punto, desembarazado de la influencia de los campos magnéticos perturbadores, estando relacionados la primera distancia x, la distancia delta x entre dichos puntos primero y segundo, el primer coeficiente de proporcionalidad k1, el segundo coeficiente de proporcionalidad k1, el segundo coeficiente de proporcionalidad k2, dicho factor fi y la relación ro entre las intensidades de los campos magnéticos perturbadores, en dicho segundo punto y en dicho primer punto, respectivamente, por las fórmula delta x= x (raíz cúbica de ro-1) y k2.fi/k1=x/3
