Cuando una bobina gira uniformemente en el interior de un campo magnético uniforme se genera una corriente eléctrica, éste es el fundamento del alternador.

Concepto de amplitud de ondas

En este problema, se utiliza la idea de campo (en nuestro caso gravitatorio) y se ve cómo varía dicho campo en el espacio que rodea una masa extensa (la Tierra), en su superficie, y en los puntos del interior de la misma.
