Physics-Magnetic Properties of Materials
NEET Physics Magnetic Properties of Materials Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): In ferromagnetic materials, the relation between magnetic induction (B) and magnetic field strength (H) is complex and often non-linear. | Reason (R): The maximum dipole moment in a ferromagnetic domain is achieved when all atomic moments are perfectly aligned.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option B
Detailed Explanation
Both the assertion and reason are true, but the reason does not explain the complexity of the B-H relationship in ferromagnetic materials. The complexity arises due to factors like hysteresis and domain wall movement.
