\nFerromagnetic materials exhibit hysteresis. When a magnetic field is applied, they become strongly magnetized. When the applied magnetic field is removed, a significant amount of magnetization often remains, even if the external field is reduced to zero. This retained magnetization is called remanent magnetization or remanence. This property allows ferromagnetic materials to be used to create permanent magnets.
\n<\/section>\n
\n– Ferromagnetic materials show hysteresis in their magnetization curve.
\n– Remanence is the residual magnetization left after the applied field is removed.
\n– This property is essential for creating permanent magnets.
\n<\/section>\n
\nMagnetization in ferromagnetic materials is caused by the alignment of magnetic domains. Applied fields cause domains oriented with the field to grow and those opposed to shrink. Even after the external field is removed, some of this alignment persists due to the strong internal interactions between domains.
