Abstract

A new high-Tc bulk magnet system, which consists of five aligned superconducting bulks, has been developed for the magnetic separation to purify waste water. Five GdBaCuO bulk blocks are cryo-cooled down to 40 K from the side face (along ab-plane) and are magnetized in turn by the pulse field magnetizing using a split-type pulse coil with the applied field of Bex = 5.0-5.5 T. The trapped field BTP ∼ 2.0 T can be attained on the bulk surface and the BT6 mm, 6 mm distant above the bulk surface in the open space, is 1.0-1.2 T for each bulk. The results for the temperature rise and trapped field are compared with those for the same bulk cooled down along the c-axis and magnetized using a solenoid-type pulse coil.
