NEET Physics Magnetic Properties of Materials MCQ Question
Which of the following statements about magnetic properties of materials is correct?
Ferromagnetic materials retain magnetization after the external field is removed.
All ferromagnetic materials are hard magnetic materials.
The magnetization in ferromagnetic materials is always linear with respect to the applied magnetic field.
Soft ferromagnetic materials do not retain magnetization after the external field is removed.
Correct Answer
Detailed Explanation
Ferromagnetic materials exhibit a property where they can retain magnetization even after the external magnetic field is removed, which defines hard magnetic materials, as mentioned in the context. Options B and C misrepresent the nature of ferromagnetic materials, and D incorrectly classifies soft ferromagnetic materials.
