NEET Physics Magnetic Properties of Materials MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a diagram showing a bar of paramagnetic material placed in an external magnetic field . Which of the following correctly describes the behavior of the field lines within the material?
A
The field lines are slightly concentrated inside the material.
B
The field lines are completely expelled from the material.
C
The field lines remain unchanged inside the material.
D
The field lines are highly concentrated, increasing by several orders of magnitude.
Correct Answer
Option A
Detailed Explanation
In a paramagnetic material, the external field lines are slightly concentrated inside the material due to the alignment of atomic dipoles, enhancing the field by a small amount, typically one part in 10^5.
