Magnetic hysteresis is exhibited by magnetic materials which are

Step-by-step solution

Magnetic hysteresis occurs when a material's magnetization depends on its magnetic history, not just the current applied field, resulting in a characteristic lag that forms a hysteresis loop when plotted. This phenomenon is exclusive to ferromagnetic materials, which contain permanent magnetic dipoles organized into domains. Under an external magnetic field, these domains align and grow, producing strong magnetization. When the field is removed, residual magnetization (retentivity) persists due to sustained domain
