NEET Physics Magnetic Properties of Materials MCQ Question
Which of the following statements about magnetic properties of materials is correct?
The magnetic field inside a solenoid filled with magnetic material is greater than the field produced by the solenoid alone.
Magnetisation M of a material is independent of the magnetic field intensity H applied to it.
The additional magnetic field Bm contributed by a material is inversely proportional to its magnetisation M.
The relationship between B and H in ferromagnetic materials is always linear.
Correct Answer
Detailed Explanation
The first statement is correct as the text states that the field inside a solenoid filled with a material with non-zero magnetisation is greater than B0. The second, third, and fourth statements reflect misconceptions regarding magnetisation and the relationship between B and H.
