¿Cómo funciona un fonocaptor de imán móvil (MM)?

En un cartucho de imán móvil, la aguja se desplaza por el surco de un disco, transfiriendo su fuerza mecánica del cantilever a un imán conectado al otro extremo.

El cantilever y el imán se mueven (imán móvil), interactuando con una bobina para generar una señal electromagnética. La señal sale a través de cuatro pines situados en la parte posterior del cartucho. Audio-Technica utiliza dos imanes y varias bobinas (diseño de doble imán móvil) para leer con mayor precisión ambos lados (canales izquierdo y derecho) del surco del disco.
