NEET Physics Magnetic Properties of Materials Assertion Reason Question
Assertion (A): In ferromagnetic materials, the sample tends to move towards the region of high magnetic field.
Reason (R): In ferromagnetic materials, the field lines are highly concentrated, and the magnetisation may persist even after the external field is removed.
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
Ferromagnetic materials tend to move towards regions of high field due to the concentration of magnetic field lines and can remain magnetised after the external field is removed, as explained by the persistence of magnetisation.
