NEET Physics Magnetic Properties of Materials MCQ Question
Which of the following statements about the magnetic properties of materials is correct?
Magnetic monopoles can exist as isolated entities in nature.
The magnetic field inside a solenoid filled with a material with non-zero magnetization is greater than the field produced by the solenoid alone.
The magnetic flux through any closed surface is always positive.
The alignment of magnetic field lines is independent of the material properties when placed in a magnetic field.
Correct Answer
Detailed Explanation
According to the NCERT context, when a solenoid is filled with a material that has non-zero magnetization, the net magnetic field inside the solenoid increases due to the contribution from the material core, making option B correct.
