The remanence of {ital N}{times}{ital N} square-columnar Josephson-junction arrays with normalized maximum junction current {ital i}{sub max} is calculated from the dc and ac Josephson equations, the Ampere theorem, and the gauge invariance. A transition line on the {ital i}{sub max-}{ital N} plane is obtained, on the high-{ital i}{sub max} side of which the remanence is nonzero. It is found that in the nonzero remanence state the symmetry degree of field profile can be lower than expected by intuition. The meaning and importance of this finding are discussed.
