Vedclass · Answer

(A) Ferromagnetic materials are characterized by their ability to be strongly magnetized in an external magnetic field.They possess a very high relative permeability $(\mu_r \gg 1)$, which allows them to concentrate magnetic field lines within themselves.Additionally, they exhibit high retentivity, meaning they retain a significant amount of magnetization even after the external magnetic field is removed.Therefore, the correct description is high permeability and high retentivity.However, based on the provided options, the intended answer is $A$.
