The rotation speed of the tube in the ball milling method affects the crystalline size and magnetic properties of the natural sand sample used. Identification of elemental content in natural sand was carried out using ...

Analysis of the magnetic susceptibility of the composition and particle size of the natural sand of the Rokan River has been carried out using two-stage ball millng method.This study aims to determine the value of magnetic ...

Magnetically soil contamination can be caused by motor vehicle emussions of exhaust, where friction between the tire and the road surface cause magnetic particles. This study was aimed to characterize of the magnetic ...
