NEET Physics Magnetic Properties of Materials Assertion Reason Question
Assertion (A): A solenoid filled with a ferromagnetic material has a higher magnetic field inside than an empty solenoid. | Reason (R): The magnetic field contributed by the material core is proportional to its magnetisation.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
The NCERT context explains that the field inside a solenoid with a material core is greater due to the additional field Bm, which is proportional to the magnetisation M of the material.
