There are different methods for recording properties of magnetic materials. Magnetic property material means recording the magnetization curve, hysteresis, degaussing curve and permeability. There are alternating and direct current measurement methods. Selecting the measurement method depends on the shapes, sizes, patterns, speed and accuracy of measurements and the required size of the measuring field , because in soft magnetic materials should allow the measurement of fields smaller than, and in hard bigger than. In the ballistic method with ring pattern considers the process of recording the magnetization curve on a sample of annular shape. In stick samples, it uses large sections yoke of the magnetic material, and that it"s the Hopkins yoke. Fahy-Simplexov permeameter is a device which determines the strength of the magnetic field by measuring the magnetic low voltage drop. , Also with Iliovicievs yoke, the sample of magnetic field intensity it is determined with meas mag low volt. Same method is used in measuring the stronger fields, above , and it is a special type of sample that is very narrow in the measuring part. This method is not suitable for the determination of the hysteresis loop, so in practice its used the Istmo method with pole ext. Stäblein-Steinitzov device with methods of determining the magnetic characteristics is used with rotating or vbrtg coil and its suitable fr cur mes in prod.
