In passive voice, the sentence "The hammer might have struck him" is transformed by making the object of the active sentence (him) the subject of the passive sentence, using the appropriate form of the verb "to be" (in this case, "been") and the past participle of the main verb (struck). The modified sentence in passive voice is: "He might have been struck by the hammer." In this passive construction, the emphasis is on the receiver of the action (him), rather than the doer of the action (the hammer). The subject of the passive sentence (him) is now affected by the action of being struck by the hammer.
