Understanding Magnetic Substances
Magnetic materials can be classified into different categories based on their magnetic properties. Among these categories, ferromagnetic substances stand out for their ability to become highly magnetized in the presence of an external magnetic field.
1. Ferromagnetic Substances
- Ferromagnetic substances, such as iron, cobalt, and nickel, have unique properties that allow them to be strongly attracted to magnets.
- When placed in an external magnetic field, the magnetic domains within these materials align in the direction of the field, significantly increasing their overall magnetization.
- This alignment persists even after the external magnetic field is removed, leading to permanent magnetization.
2. Antiferromagnetic Substances
- Antiferromagnetic substances have magnetic moments that align in opposite directions within the material, canceling each other out.
- As a result, they do not exhibit a net magnetization in an external magnetic field.
3. Paramagnetic Substances
- Paramagnetic substances, like aluminum and platinum, exhibit weak attraction to magnetic fields.
- Their magnetic moments align with the external field but do not retain magnetization after the field is removed.
4. Diamagnetic Substances
- Diamagnetic substances, such as bismuth and copper, exhibit a very weak repulsion to magnetic fields.
- Their magnetic properties arise from the motion of electrons, which create a magnetic field opposite to the applied field.
Conclusion
In summary, among the listed options, ferromagnetic substances are the only ones that become highly magnetized in an external magnetic field, making option 'A' the correct choice. Understanding these distinctions is crucial for applications in electronics, data storage, and magnetic materials.

Ferromagnetic substances are those substances which are strongly magnetized in an external magnetic field in the same direction as the external applied field and retain its magnetic moment even after the removal of external field. They have very strong tendency to move from weaker to the stronger parts of the external field. Iron, cobalt, nickel, etc are examples of ferromagnetic substances.
