    Penentuan Nilai Suseptibilitas Magnetik Pasir Besi Pantai Pariaman Sumatra Barat Dengan Menggunakan Magnetic Probe Pasco 2126
    (2015-10-26) Erwin; Malik, Usman; Fahmi, Amril
    Measurement of magnetic properties especially magnetic degree and susceptibility of iron sand along Pariaman Beach ,West Sumatra such as Arta, Gandoriah, Kata, Nareh, and Tiku beach has been done. Total magnetic induction of the concentrate was measured using Pasco magnetic probe PS-2126. The results show that the value of magnetic degree of the samples varies in the range of 3,07 to 10,98 %. This variation reflects the different process in the formation of the iron sand and is related to the topology of the beach. The value of magnetic susceptibility of the concentrate varies from 4,97 x 10-4 m3/kg to 6,34 x 10-4 m3/kg. The highest and lowest value of magnetic susceptibility is originated from Kata and Nareh beach that are 6,34 x 10-4 m3/kg and 4,97 x 10-4 m3/kg respectively. These values are in the range of magnetic susceptibility of magnetic particles of Fe3O4.
