Question

Directions: The question consists of two statements, one labeled as ‘Statement (I)’ and the other labeled as ‘Statement (II)’. You are to examine these two statements carefully and select the answers to these items using the codes given below:

Statement (I): A diamagnetic material has no permanent dipoles.

Statement (II): Paramagnetic material has the antiparallel orientation of equal moments with neighboring dipoles.

1. Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I).
2. Both Statement (I) and Statement (II) are individually true, but Statement (II) is not the correct explanation of Statement (I).
3. Statement (I) is true, but Statement (II) is false.
4. Statement (I) is false, but Statement (II) is true.
5.

Answer 1

Correct Answer - Option 3 : Statement (I) is true, but Statement (II) is false.

• Diamagnetic material has no permanent dipole.
• Diamagnetic materials have induced dipoles.
• Paramagnetic materials atomic dipoles are randomly oriented such that, in absence of external field net magnetization is zero
• Ferromagnetic materials  have anti-parallel orientation of unequal moments such that they have some magnetization in absence of external field.
• Anti ferromagnet materials have, anti-parallel orientation of equal moment such that net  magnetization is zero.
