NEET Physics Magnetic Properties of Materials MCQ Question
Which of the following statements about ferromagnetic materials and their behavior in magnetic fields is correct?
Ferromagnetic materials can retain magnetization even after an external magnetic field is removed.
Ferromagnetic materials exhibit no net magnetization due to thermal motion of the atoms.
Ferromagnetic materials do not respond to external magnetic fields.
Ferromagnetic materials have a magnetic susceptibility that is always negative.
Correct Answer
Detailed Explanation
Ferromagnetic materials can retain their magnetization even after the external field is removed, making them hard magnetic materials, as noted in the context provided. This is in contrast to paramagnetic materials, which do not retain magnetization.
