Yes.

While a literal translation of the 'jin' part is indeed array; in the context of magic it almost always means circle. js06 says that he always translates the term as magic circle.

The array part refers to the complex pattern that is drawn. Sometimes this leads to other strange, out-of-context translations like magic square, which is a mathematical thing rather than a magical one!
