Let A*=A-{0}.A function f:E(G) A* is called a labeling of G. Any labeling induces a map f+ : V(G) A, defined by f+(v)= = distinct ,where u,v ϵ E(G).In this paper,weexamine,theDC-magic spectra of class of  graphs such as cycle,star,path,k1+P3,C4@Sn,C6@Sn,C10@Sn,C12@Sn,where n is odd.The conjecture that the even cycle C2n @Sn whose distinct magic spectrum is Zn.
