Persuasion is act/strategy that is applied on someone by something or somebody with the goal of changing one's belief or attitude towards something while inquiry does not have the goal of changing one's belief about something but instead it is a strategy used to learn more about one's attitude or belief towards something
therefore the main difference between inquiry and persuasion is that
persuasion attempts to influence beliefs or attitudes, and requests some type of action from listeners. and not vice versa as stated in the question
