Abstract

PURPOSE: To measure magnetic characteristics of a long-bar-shaped permanent magnet material in a short time without destruction, by using a cylindrical magnetizing coil and magnetic-field detector.
CONSTITUTION: The magnetic-field detector consists of cylindrical magnetizing coil 2 of a single layer, Hall element 4 and gauss meter 5. Long-bar-shaped permanent magnet material 1, produced one after another by hot work, such as an Mn- Al-C alloy magnet is coaxially inserted into cylindrical magnetizing coil 2 and the magnetic-field detector is arranged near cylindrical magnetizing coil 2 to magnetize the long-bar-shaped permanent magnet material, thereby detecting the distribution of magnetic flux 3 on the surface of long-bar-shaped permanent magnet material 1 by Hall element 4. Thus, magnetic characteristics of material 1 can be measured in a short time without cutting the sample.
