Magnetic properties of matterHard
Question
Given below are two statements : one is labelled as
Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The individual atoms in a
ferromagnetic material possess a magnetic dipole moment and interact with one
another in such a way that they spontaneously align themselves forming domains.
Reason (R) : At high enough temperature, the domain structure of ferromagnetic
material disintegrates. Thus, magnetization will disappear at high enough
temperature known as Curie temperature.
In the light of the above statements, choose the correct answer from the
options given below :
Options
A.(A) is true but (R) is false
B.Both (A) and (R) are true but (R) is not the
correct explanation of (A)
C.Both (A) and (R) are true and (R) is the correct
explanation of (A)
D.
(A) is false
but (R) is true
