There are a few differences I have found between Journals and Magazines. Journals typically feature research by Professors or Specialists whereas Magazine articles are typically written by non-specialists who are hired for writing. Journals generally go through a peer review and Magazines will just go through an Editor who may or may not have alternative motives. Journals usually will have bibliographies and Magazines will not. Last, but not least, Journals will have minimized advertising whereas Magazines will have over the top pictures and their ulterior motives for all to see.
