You can organize a magazine article rudimentarily as a sandwich: two slices of experience or reporting or essay filled with a primer on the subject under discussion. I used that structure in desperation more than once and even got by with it. More sophisticated organization requires interweaving. The best way to do that is to let your narrative determine when you stop and fill in the basics. You find something in your research that you believe readers will recognize and use that to open the story. When you come to a point that's likely to be unfamiliar, you cut away long enough to explain the context, then cut back to narrative, and so on through the article.
