We made a AgMg/Bi2212 magnet for investigation of the mechanical and superconducting properties under the large electromagnetic stress. The coil was reinforced by the cowinding technique with Hastelloy tapes. The strain values at the operation current of 275 A was about 0.25% for a coil reinforced by one Hastelloy tape but 0.1% for that reinforced by three Hastelloy tapes. In addition, the rapid increase of voltage was observed, when the operation current reaches to 275 angstrom. The stability of the test magnet is discussed.
