PENENTUAN TINGKAT KEMAGNETAN DAN INDUKSI MAGNETIK TOTAL ENDAPAN PASIR LAUT PANTAI PADANG SEBAGAI FUNGSI KEDALAMAN

Abstract

We report the determination of the stage of magnetism and magnetic induction iron sand deposits as a
function of depth in Padang, West Sumatra coast. Samples of the iron sand deposits are dried first,
then the separation concentrate iron sand with sand using iron sand separator apparatus to identify the
element countain of sampels then it was used XRF ( X- Ray Fluerensence). The study results
expressed that grades stage magnetism iron sand deposits increases or increases as a function of
depth, where the value of stage magnetism obtained by the ratio between the mass of the sample mass
concentratet. The value of magnetic induction total measured using a magnetic sensor Pasco PS-2162
through a solenoid made of 2500 loops with a length of 8 cm and a diameter of 2,5 cm were
electrified by the variation of a current of 2 A to 10 A and a horizontal distance of 1 to 5 mm along
the axis solenoid. When an electric current is increased, the greater the total magnetic induction, and
the total value of magnetic induction decreases as a function of the horizontal distance.
