Which magnetic material property is characterized by a large positive magnetic susceptibility and the retention of magnetization even after the external magnetic field is removed?

💡 Solution & Explanation

Ferromagnetic materials exhibit strong positive magnetic susceptibility and retain permanent magnetic moments after external fields are withdrawn due to cooperative alignment within magnetic domains. Diamagnetic substances possess small negative susceptibilities and are weakly repelled by magnets. Paramagnetic materials have small positive susceptibilities and align weakly with external fields without permanent retention. Antiferromagnetism features adjacent atomic magnetic moments aligned in opposite directions resulting in zero net magnetization.
