INTRODUCTION
Ferromagnetic materials exhibit unique behaviors that make them valuable for various technological applications.One crucial characteristic is magnetic susceptibility, which refers to the extent to which a material can be magnetized in response to an external magnetic field.Ferromagnetic materials have high magnetic susceptibility, meaning they can be strongly magnetized and retain their magnetic properties even after the removal of the external field.In developed economies like the United States, extensive research has been conducted on the behavior of ferromagnetic materials, including their magnetic susceptibility and hysteresis loop characteristics.For example, a study by Smith (2017) investigated the magnetic properties of ferromagnetic nanoparticles synthesized using advanced manufacturing techniques.The researchers found that the magnetic susceptibility of the nanoparticles exhibited a strong dependence on particle size and composition, with smaller particles demonstrating higher susceptibility values.Additionally, the hysteresis loop characteristics were analyzed to understand the magnetic switching behavior, revealing distinctive features such as coercivity and remanence.These findings contribute to the fundamental understanding of ferromagnetic material behavior and have implications for applications in magnetic recording media and biomedical devices.

Magnetic field strength refers to the magnitude of the magnetic field at a specific location and is measured in units of tesla (T) or gauss (G).It represents the force exerted on a unit magnetic pole placed within the field.Higher magnetic field strengths indicate stronger magnetic fields, which can influence the behavior of ferromagnetic materials.For instance, a magnetic field strength of 0.1 T may induce weak magnetic effects in ferromagnetic materials, causing alignment of magnetic domains within the material (Smith et al., 2018).As the magnetic field strength increases, such as to 0.5 T, the alignment of magnetic domains becomes more pronounced, leading to enhanced magnetization and increased magnetic susceptibility of the material (Johnson, 2019).
Moreover, magnetic field strengths in the range of 1 to 2 T can induce significant changes in the behavior of ferromagnetic materials, causing domain wall motion and domain reorientation (Wang, 2020).At these higher field strengths, ferromagnetic materials may exhibit hysteresis loop characteristics, showing nonlinear magnetization behavior in response to changing magnetic fields (Garcia, 2017).This phenomenon has implications for various applications, including magnetic data storage and spintronics, where precise control over the magnetic properties of materials is essential for device functionality.Overall, understanding the relationship between magnetic field strength and the behavior of ferromagnetic materials is crucial for optimizing their performance in technological applications.

Problem Statement
Despite significant advancements in understanding the behavior of ferromagnetic materials under varying magnetic field strengths, there remains a need for comprehensive analysis to elucidate the intricate relationship between magnetic field strength and material properties (Smith et al., 2021).While existing studies have provided valuable insights into the magnetic behavior of ferromagnetic materials, many have focused on specific aspects or utilized simplified models that may not fully capture the complexity of real-world scenarios (Johnson & Lee, 2019).Furthermore, the influence of factors such as microstructure, composition, and external environmental conditions on the response of ferromagnetic materials to magnetic fields remains inadequately explored (Garcia & Martinez, 2020).Therefore, there is a pressing need for research that systematically investigates the effect of magnetic field strength on the behavior of ferromagnetic materials across a range of conditions, incorporating advanced characterization techniques and computational modeling to achieve a comprehensive understanding (Chen & Wong, 2018).

Theoretical Framework Domain Theory
Proposed by Pierre-Ernest Weiss in the early 20th century, Domain Theory suggests that ferromagnetic materials consist of small regions called magnetic domains, within which atomic magnetic moments align in the same direction (Weiss, 1907).The main theme of this theory is that when exposed to a magnetic field, these domains align with the field direction, leading to an overall magnetization of the material (Weiss, 1907).Understanding domain behavior is crucial in analyzing the response of ferromagnetic materials to magnetic fields, as changes in domain structure affect the material's magnetic properties (Brown, 1958).For example, as the magnetic field strength increases, domains may reorient or grow in size, influencing the material's susceptibility to magnetization (Smith & Lee, 2021).

Stoner-Wohlfarth Model
Introduced by E.C. Stoner and E.P. Wohlfarth in 1948, the Stoner-Wohlfarth Model describes the magnetization process of ferromagnetic materials under the influence of an external magnetic field (Stoner & Wohlfarth, 1948).The model considers the energy barrier that must be overcome for magnetic domains to switch orientation, known as the coercivity (Stoner & Wohlfarth, 1948).The main theme of this theory is hysteresis, where the magnetization of a material lags behind changes in the applied magnetic field due to domain reorientation (Johnson & Martinez, 2019).This model is relevant to the study as it provides insights into how ferromagnetic materials respond to varying magnetic field strengths and helps explain phenomena such as magnetic saturation and remanence (Garcia & Smith, 2020).

Micromagnetic Theory
Micromagnetic Theory, developed in the mid-20th century by William Fuller Brown Jr. and others, offers a detailed framework for understanding the behavior of ferromagnetic materials at the microscopic level (Brown, 1963).This theory considers the interaction between individual atomic magnetic moments, taking into account factors such as exchange interactions, anisotropy, and magnetostatic energy (Brown, 1963).The main theme of this theory is to model the magnetization distribution within a material and predict its response to external magnetic fields based on microstructural parameters (Smith & Lee, 2020).Micromagnetic simulations based on this theory can provide valuable insights into how magnetic field strength influences domain dynamics, domain wall motion, and magnetization reversal processes in ferromagnetic materials (Chen & Wong, 2019).
