Question
Physics Question on Magnetic properties of materials
The temperature at which ferromagnetic material becomes paramagnetic is called a
A
neutral temperature
B
Curie temperature
C
inversion temperature
D
critical temperature
Answer
Curie temperature
Explanation
Solution
Ferromagnetism decreases with rise in temperature. If a ferromagnetic substance is heated, then at a definite temperature the ferromagnetic property of the Substance suddenly disappears and the substance becomes paramagnetic. The temperature above which a ferromagnetic substance becomes paramagnetic is called Curie temperature.
