Karakterisasi Material Logam Berdasarkan Sifat Magnetik Menggunakan Kurva Magnetisasi

---

Technological 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 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). 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 the susceptibility
value will decrease so that the magnetic field B obtained from the measurement is
getting smaller.
