This is how I see it: The primary antagonist (or the main antagonist) is the one who provides most of the story arc/conflict for the protagonists, and he/she has bigger plans than everyone else. The secondary antagonist, while having a major role, has smaller plans and usually operates as the primary antagonist's right-hand man. In Harry Potter, Voldemort was the one who shaped most of Harry's life by murdering his parents and relentlessly antagonizing him, while Professor Quirrel is simply a pawn who follows Voldemort's orders.
