Abstract

Un método para determinar la cantidad de partículas magnéticas dentro de una muestra utilizando un circuito sintonizado que tiene un capacitor (C) y unabobina (L). El método comprende A) determinar la diferencia en la frecuencia resonante del circuit o sintonizado cuando la muestra es expuesta a un campomagnético generado pr la bobina y cuando la muestra no es expuesta al campo magnético generado por la bobina; y b) utilizar la diferencia en la frecuenciaresonante para determinar la cantidad de p artículas magnéticas dentro de la muestra.
