1. Ferromagnetism - The substances that are strongly attracted by a magnetic field are known as ferromagnetic substances. So, from the given options - CrO₂.
2. Ferrimagnetism - Ferrimagnetic substances are weakly attracted by a magnetic field as compared to ferromagnetic substances. Magnetite (Fe₃O₄).
3. Anti-ferromagnetic - The domains of antiferromagnetic substances are oppositely oriented and cancel out each other's magnetic moment. MnO₂, MnCl₂.
CuFe₂O₄ and CrBr₃ are usually classified as para-magnetic susbtances.
