What is claimed is: 1 . A coil electronic component comprising: a magnetic body containing a ferrite; and a coil part including a plurality of conductive patterns disposed in the magnetic body, wherein the ferrite contains: 48 to 50 mol % of iron oxide calculated in terms of Fe 2 O 3 , 8 to 12 mol % nickel oxide calculated in terms of NiO, 28 to 31 mol % zinc oxide calculated in terms of ZnO, and 7 to 13 mol % copper oxide calculated in terms of CuO. 2 . The coil electronic component of claim 1 , wherein 2.6≦c/b≦3, where b is a mol % of the nickel oxide, and c is a mol % of the zinc oxide. 3 . The coil electronic component of claim 1 , wherein 2.4≦c/d≦3.3, where c is a mol % of the zinc oxide, and d is a mol % of the copper oxide. 4 . The coil electronic component of claim 1 , wherein 2.6≦c/b≦3 and 2.4≦c/d≦3.3, where b is a mol % of the nickel oxide, c is a mol % of the zinc oxide, and d is a mol % of the copper oxide. 5 . The coil electronic component of claim 1 , wherein the magnetic body comprises a plurality of sintered laminated magnetic layers containing the ferrite. 6 . A coil electronic component comprising: a magnetic body containing a ferrite; and a coil part including a plurality of conductive patterns disposed in the magnetic body, wherein the ferrite consists essentially of aFe 2 O 3 -bNiO-cZnO-dCuO, wherein 2.6≦c/b≦3 and 2.4≦c/d≦3.3. 7 . The coil electronic component of claim 6 , wherein 48≦a≦50, 8≦b≦12, 28≦c≦31, and 7≦d≦13.
