Love (in its broadest meaning) is depicted as a particularly powerful form of magic. According to Dumbledore, love is a "force that is at once more wonderful and more terrible than death, than human intelligence, than forces of nature." Lily's voluntary sacrifice on Harry's behalf saves him from Voldemort as a baby, and Harry makes a similar sacrifice to save his friends at the end of "Deathly Hallows". A certain key prophecy in the series describes Harry as having "power the Dark Lord knows not", referencing his capacity for love.
