Assertion: Ferromagnetic substance exhibits spontaneous magnetisation.
Reason: In the absence of external magnetic field, atomic dipoles of each domain are aligned in particular direction.

View answer and explanation

Correct option: A

If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion

Option A (If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion) is correct because ferromagnetic materials exhibit spontaneous magnetization due to aligned atomic dipoles within domains, even without an external field.
