Abstract

Ferromagnetic materials are a fascinating class of substances that exhibit extraordinary magnetic properties. This article delves into the world of ferromagnetism, explaining the fundamental principles that underlie this unique behavior. We explore the alignment of atomic magnetic moments within these materials, resulting in their capacity to become permanently magnetized. Key characteristics such as saturation magnetization, remanence, coercivity, and the Curie temperature are elucidated. Furthermore, we discuss the practical applications of ferromagnetic materials, including their role in permanent magnets, magnetic data storage, transformers, MRI machines, electromagnets, and magnetic sensors. Understanding the magnetic properties of ferromagnetic materials is crucial for harnessing their potential and advancing technology
