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)
The correct answer is:
Option 3: (B), (A), (C)
Consider the following statements:
A. The junction area of a solar cell is made very narrow compared to a photodiode.
B. Solar cells are not connected with any external bias.
C. LED is made of lightly doped p-n junction.
D. Increase of forward current results in a continuous increase in LED light intensity.
E. LEDs have to be connected in forward bias for emission of light.
