dc.description.abstractTechnological developments in the industrial sector have made very significant progress, one of which is in the material processing industry for metal sorting originating from metal material waste. In this study, a metal type determination system was developed based on the susceptibility value of the magnetization curve. This magnetization curve instrument is a magnetic field measuring instrument that functions to inspect metal materials in a simpler and more practical way. The conventional method uses an electromagnet system to separate metallic materials, however, this method can only detect metals with a susceptibility value. The materials used are aluminum, copper, and iron, which already represent the magnetic properties of metallic materials. This measurement uses a current of -0.5 A to 0.5 A and uses a frequency that is varied by 1, 10, and 100 Hz. The measurement results show that copper material which represents diamagnetic properties with a frequency of 1 Hz produces a susceptibility value of -2.2 x 10-3 (a.u), while for a frequency of 10 Hz it produces a value of -2.1 x 10-3 (a.u). And for a frequency of 100 Hz, the value is -23 x 10-3(a.u). The second material is aluminum which represents paramagnetic properties using a frequency of 1 Hz and then produces a susceptibility value of 2 x 10-3(a.u), then using a frequency of 10 Hz produces a value of 1.3 x 10-3 (a.u) and a frequency of 100 Hz produces a value of 8,6 x 10-3 (a.u) and the third iron material which represents ferromagnetic properties with the same treatment using a frequency of 1 Hz produces a susceptibility value of 4.43 (a.u), for a frequency of 10 Hz produces a value of 4.42 (a.u) and a frequency of 100 Hz produces a value of 4.46 (a.u). The conclusion in this study is that there are differences in the responses of the tools designed to the type of magnetic material being tested where the diamagnetic susceptibility values are small and negative, the paramagnetic susceptibility values are small and positive, and the ferromagnetic susceptibility values are large and positive. In addition, the effect of frequency on the measurement is also obtained where the greater the frequency of the measurement where the greater the frequency used, the susceptibility value will decrease so that the magnetic field B obtained from the measurement is getting smaller.en_US
