Micro-magnetic modeling is a computational methodology and research field dedicated to simulating and understanding the magnetic behavior of materials at the microscale. It involves the numerical solution of continuum or atomistic models describing magnetization dynamics and static configurations, typically employing methods like finite differences or finite elements implemented in specialized software packages. This approach investigates phenomena such as domain formation, domain wall motion, and magnetization reversal processes. Its significance lies in providing detailed insights into complex magnetic systems, guiding the design and optimization of magnetic materials and technological devices.
