Abstract

A permanent magnet is a hard-ferromagnetic material with a large remnant magnetization and a high coercive field which allows its use as a static field source. In this work, we studied the magnetic properties behavior of the hexaferrite material BaFe12O19 as a function of the external magnetic field at two selected values of temperature T=298K and T=358K, for different magnetic field directions on the easy-axis of magnetization and the hard-axis of magnetization in order to analyze the effect of anisotropy energy on the saturation magnetization using the simulation method. We elaborated a permanent magnet from local BaFe12O19 hexaferrite material by a prototype proposal, using experimental equipment to create a sufficiently high magnetic field permitting us to approach the saturation magnetization value of this material.
