DESCRIPTION OF THE PROCESS OF MAGNETIZATION OF HOLLOW CYLINDRICAL RODS FROM SOFT MAGNETIC MATERIALS IN A HOMOGENEOUS QUASI-STATIC MAGNETIC FIELD OF A SOLENOID. HYSTERESIS LOOP
V. F. Matyuk, A. A. Osipov, and A. V. Strelyukhin UDC 620.179.14 On the basis of the arctangential approximation of the magnetic hysteresis loop of the material and the expression for the central demagnetization coefficient of hollow cylindrical rods from soft magnetic materials, a method for calculating the hysteresis loops of these rods in a homogeneous quasi-static field of a solenoid is proposed. Calculation and comparison to experimental data of the basic parameters of the magnetic loops hysteresis of hollow cylindrical rods with a different value of the demagnetization coefficient have been made.
