Physics Question on Electrical Instruments
When the temperature exceeds the transition temperature, a ferromagnetic material becomes similar to:
A
(A) Anti-ferromagnetic material
B
(B) Diamagnetic material
C
(C) Ferrimagnetic material
D
(D) Paramagnetic material
Answer
(D) Paramagnetic material
Explanation
Solution
Explanation:
When the temperature exceeds the transition temperature, a ferromagnetic material becomes similar to paramagnetic material because randomness in the orientation of dipoles increases due to increased temperature and ferromagnetic material lose their magnetic property.
Hence, the correct option is (D).
