- (A), (B), (C)
- (C), (A), (B)
- (B), (A), (C)
- (B), (C), (A)
The Correct Option is C
Approach Solution - 1
To arrange the magnetic materials by increasing magnetic susceptibility, we need to understand their properties. Magnetic susceptibility (\(\chi\)) quantifies how much a material will become magnetized in an applied magnetic field. The order of magnetic susceptibility for different types of magnetic materials is as follows:
- Diamagnetics: These materials have a small negative magnetic susceptibility. They are weakly repelled by magnetic fields.
- Paramagnetics: These materials have a small positive magnetic susceptibility. They are weakly attracted to magnetic fields.
- Ferromagnetics: These materials have very high positive magnetic susceptibility. They are strongly attracted to magnetic fields and can retain magnetization even after the external field is removed.
Based on these descriptions, the order of increasing magnetic susceptibility is: (B) Diamagnetics, (A) Paramagnetics, (C) Ferromagnetics
This corresponds to the option: (B), (A), (C)
Approach Solution -2
To arrange the magnetic materials in increasing order of magnetic susceptibility, we need to understand the characteristics of each type:
Diamagnetics (B): These materials have paired electrons and are weakly repelled by magnetic fields. They have a small, negative magnetic susceptibility.
Paramagnetics (A): These materials have unpaired electrons and are weakly attracted by magnetic fields. They have a small, positive magnetic susceptibility.
Ferromagnetics (C): These materials have strong magnetic properties due to the alignment of magnetic domains. They have a large, positive magnetic susceptibility.
Therefore, the increasing order of magnetic susceptibility is:
Diamagnetics < Paramagnetics < Ferromagnetics
Which corresponds to: (B), (A), (C)
