A new type of "persistent-mode" magnet, assembled from YBCO annuli, appears promising for "microcoil" NMR, in which compactness and simple manufacturability are vital. To develop an annular magnet for micro NMR, a YBCO-annulus Helmholtz coil was studied. The paper describes the new magnet concept and results of our study on the Helmholtz coil.
