Question

Which of the following property shows the property of ferromagnetic substances?

• A. The ferromagnetic property depends on temperature.
• B. The ferromagnetic property does not depend on temperature.
• C. At high enough temperature ferromagnet becomes a diamagnet
• D. At low temperature ferromagnet becomes a paramagnet

Answer 1

Answer: (A)

The ferromagnetic property depends on temperature.

Ferromagnetic material depends on temperature as for $T<T_c\left(Curi{e}^{\prime }sTemperature\right)$ it acts as a ferromagnet.

$T>T_c$ acts as a paramagnet.
