Penentuan Sifat Magnetik Dan Morfologi Nanopartikel Oksida Besi Pasir Alam Lo…

The purpose of this study is to determine the magnetic properties and morphology of iron oxide nanoparticles of natural sand collected form Logas Village, Kuantan Singingi Regency, which was doped with nickel. Natural sand samples were separated between magnetic and non-magnetic particles using a strong magnet Neodymium Iron Boron (NdFeB), the result of the separation is called the NdFeB p…
