Title: Demagnetizing method of magnetized powder
Inventor: SASAKI KOUTAROU
IPC: H01F13/00
Filed: 1982-12-13
Abstract: PURPOSE:To perform demagnetization of magnetized powders in flowing state, by a method wherein alternating magnetic field of specified frequency is applied to the magnetized powders. CONSTITUTION:Needle magnetite having particle diameter of 1 micron, for example, when measured by a counter is disposed in water by means of ultrasonic wave and then magnetized by a magnet having the maximum magnetic field 8,500 Gauss in a container so as to obtain a specimen. Concentration of the magnetite is made 1,600ppm and frequencies of 1kHz,3kHz, 5kHz are applied to the specimen by a magnetic field generator using an air-cored coil. In this constitution, the demagnetizing effect becomes small when frequency of the magnetic field for the demagnetization is the commercial frequency or less than 1kHz, and sufficient at frequency being higher than 1kHz, particularly that higher than 3kHz.
