"the bell was rung" illustrates a cause (and introduces a question: who rang the bell?)
"the bell rang" illustrates an effect (the vibration and sound of the bell as it rings).
i think this is more an illustration of the ambiguity of the root word "ring", which can be an action by a subject upon an object, or to describe the behavior of the object itself.
