NEET Physics Magnetic Properties of Materials MCQ Question
What happens to the magnetic field inside a solenoid when it is filled with a material that has non-zero magnetisation?
The magnetic field inside the solenoid becomes greater than the external magnetic field B0.
The magnetic field inside the solenoid decreases to zero.
The magnetic field inside the solenoid remains unchanged.
The magnetic field inside the solenoid becomes weaker than the external magnetic field B0.
Correct Answer
Detailed Explanation
When a solenoid is filled with a material that has non-zero magnetisation, the magnetic field inside the solenoid is enhanced, making it greater than the external magnetic field B0, as stated in the NCERT context.
