title = "Magnetic field distribution of permanent magnet magnetized by static magnetic field generated by HTS bulk magnet",
abstract = "Demagnetized rare earth magnets (Nd-Fe-B) can be fully magnetized by scanning them in the intense static fields over 3 T of a HTS bulk magnet which was cooled to the temperature range lower than 77K with use of cryo-coolers and activated by the field of 5 T. We precisely examined the magnetic field distributions of magnetized permanent magnets. The magnetic poles were in the narrow space on the surface of the permanent magnet with varying gap distances between the tracks of the HTS magnetic pole. Steep magnetic transitions between N and S were observed in the magnetic field distribution maps after the HTS magnetic poles were alternatively scanned for several times. The magnetizing method has been proposed for designing novel electromagnetic devices including magnetically excellent rare earth magnets which require intense magnetic fields over 3 T.",
