6 Questions
Which of the following materials is diamagnetic?
Copper
Which type of magnetic behavior is exhibited by materials that are strongly attracted to a magnet and can retain their magnetization even after the external magnetic field has been removed?
Ferromagnetism
Which of the following materials is ferrimagnetic?
Manganese oxide
What is the difference between diamagnetic and paramagnetic materials?
Diamagnetic materials are those that are not magnetically attracted to a magnet, and their magnetic moment is zero, while paramagnetic materials are weakly attracted to a magnet when placed in a magnetic field.
What is the difference between ferromagnetic and ferrimagnetic materials?
Ferromagnetic materials have their magnetic moments aligned in the same direction, while ferrimagnetic materials have their magnetic moments not aligned in the same direction.
What is antiferromagnetic behavior?
Antiferromagnetic materials are those that have two magnetic sublattices, which have opposite magnetic moments and cancel each other out.
Study Notes
Magnetic Materials
- Diamagnetic materials are repelled by magnets and exhibit a weak magnetic response.
- Ferromagnetic materials are strongly attracted to magnets and can retain their magnetization even after the external magnetic field has been removed.
- Ferrimagnetic materials exhibit spontaneous magnetization, similar to ferromagnetic materials, but with a weaker magnetic response.
Key Differences
- Diamagnetic materials vs. Paramagnetic materials: Diamagnetic materials are repelled by magnets, while Paramagnetic materials are weakly attracted to magnets.
- Ferromagnetic materials vs. Ferrimagnetic materials: Ferromagnetic materials have a stronger magnetic response and can retain magnetization, while Ferrimagnetic materials have a weaker magnetic response.
Antiferromagnetic Behavior
- Antiferromagnetic behavior occurs when adjacent atoms or molecules have opposing magnetic moments, resulting in a net zero magnetic field.
