Change of Diamagnetic permeability of Copper Due To Nanosize Change

Abstract

In this work the magnetic behavior of nano copper material is studied, namely the magnetic susceptibility. Three sample of copper nano particles having three nano sizes were examined .the examination is concerned with studying the magnetic properties of them .this is done by inserting powder samples in a glass tube and then inducing magnetic field inside them by using electric coil in which magnetic flux density of each sample was measured .it was found that the diamagnetic permeability decreases as nano size is increased this may be attributed to the fact that increasing nano size decreased the number of tiny nano coils which decreases induced magnetic flux density which in turn decreases magnetic permeability.
