A graph G = (V, E) with p vertices and q edges is called edge-magic if there is a bijection f : E → {1, 2, . . . , q} such that the induced mapping f+ : V → ℤp is a constant mapping, where f+ (u) ≡ v∈N (u) f(uv) (mod p). The edge-magic index set of a graph G is the set of positive integer k such that the k-fold of G is edge-magic. In this paper, we find the edge-magic index set of the second power of a path.
