Abstract

We report the determination of the stage of magnetism and magnetic induction iron sand deposits as afunction 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 theelement countain of sampels then it was used XRF ( X- Ray Fluerensence). The study resultsexpressed that grades stage magnetism iron sand deposits increases or increases as a function ofdepth, where the value of stage magnetism obtained by the ratio between the mass of the sample massconcentratet. The value of magnetic induction total measured using a magnetic sensor Pasco PS-2162through a solenoid made of 2500 loops with a length of 8 cm and a diameter of 2,5 cm wereelectrified by the variation of a current of 2 A to 10 A and a horizontal distance of 1 to 5 mm alongthe axis solenoid. When an electric current is increased, the greater the total magnetic induction, andthe total value of magnetic induction decreases as a function of the horizontal distance.
