Which type of material exhibits negative magnetic susceptibility and is repelled by a magnetic field?

💡 Solution & Explanation

Diamagnetic materials exhibit negative magnetic susceptibility and are weakly repelled by external magnetic fields because their orbital electrons create induced magnetic fields opposing the applied field. In contrast, ferromagnetic materials like iron show strong positive susceptibility and are strongly attracted. This fundamental magnetic property is tested in examinations alongside paramagnetic and ferrimagnetic classifications.
