N(tangible/intangible) が/は passive V


A passive verb can be used when the person doing the action does not need to be mentioned.

電話は ベルに はつめいされました。×
電話は ベルによって はつめいされました。
This sentence feels strange for Japanese people because it implies we are negatively affected by Bell inventing the telephone. In order to neutralise the effect, you need to use ~によって in place of に. The verbs are often to do with creation, such as 発明“invent”, 発見“discover”, 書く“write”, etc.
