NEET Physics Magnetic Properties of Materials Assertion Reason Question
Assertion (A): In a ferromagnetic material, the magnetisation can persist even after the external magnetic field is removed.
Reason (R): Ferromagnetic materials have high retentivity, which allows them to retain a significant amount of 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
Both the assertion and reason are true. Ferromagnetic materials retain magnetisation due to high retentivity, as mentioned in the NCERT context.
