FAQs on Magnetic Properties Video Lecture - CSIR NET Crash Course for Chemical Science - CSIR NET Chemical Science

1. What are the different types of magnetic properties exhibited by materials?
Ans. Materials can exhibit paramagnetic, diamagnetic, ferromagnetic, antiferromagnetic, or ferrimagnetic properties based on their response to an external magnetic field.
2. How do paramagnetic materials behave in the presence of a magnetic field?
Ans. Paramagnetic materials are weakly attracted to a magnetic field and align their magnetic moments in the direction of the field, but the alignment is temporary and disappears when the field is removed.
3. What are the characteristics of diamagnetic materials in terms of their magnetic properties?
Ans. Diamagnetic materials are weakly repelled by a magnetic field and have all their magnetic moments paired in opposite directions, leading to no net magnetic moment.
4. Can you provide an example of a material that exhibits ferromagnetic properties?
Ans. Iron, nickel, and cobalt are examples of materials that exhibit ferromagnetic properties, where their magnetic moments align parallel to each other in the presence of a magnetic field.
5. How do antiferromagnetic materials differ from ferrimagnetic materials in terms of their magnetic properties?
Ans. In antiferromagnetic materials, neighboring magnetic moments align in opposite directions, resulting in zero net magnetic moment, whereas in ferrimagnetic materials, the magnetic moments align in opposite directions but do not cancel each other out completely.
