NEET Physics Magnetic Properties of Materials MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a diagram showing a ferromagnetic rod being magnetized by placing it in a solenoid with current passing through it. What key property of the material is crucial for selecting it as a permanent magnet in this process?
A
High retentivity
B
Low permeability
C
High coercivity
D
Low magnetic dip
Correct Answer
Option A
Detailed Explanation
For a material to be suitable as a permanent magnet, it should have high retentivity, ensuring it retains a significant amount of magnetization after the external magnetic field is removed.
