To provide a magnetic force adjustment method and device of ferrite/magnet elements, which avoids the size increase of the device and the increase of power consumption.
The magnetic force adjustment method and device of ferrite/magnet elements has an ferrite which has a plurality of center electrodes that are electrically insulated each other and crossly arranged, and permanent magnets which apply a DC magnetic field to the ferrite. The ferrite/magnet element passes through between the facing permanent magnets 63 of a magnetizing magnetic circuit member 61, so that the permanent magnet of the ferrite/magnet element is magnetically saturated. Then, the magnetically saturated ferrite/magnet element passes through a magnetic flux density distribution that is formed between the facing permanent magnets 67 of a demagnetizing magnetic circuit member 65 and simply changes, so that the permanent magnet of the ferrite/magnet element is demagnetized.
