Physics - Magnetism Question with Solution | TestHub

Magnetic hysteresis is the phenomenon where the magnetic induction ($B$) lags behind the magnetizing field ($H$). This property is a characteristic feature of ferromagnetic materials, as they retain some magnetization even after the external magnetic field is removed (retentivity) and require a reverse magnetic field to be completely demagnetized (coercivity).

Diamagnetic and paramagnetic materials do not retain magnetization in the absence of an external magnetic field and therefore do not exhibit magnetic hysteresis.

Answer: only ferromagnetic
