Physics · Para-, dia- and ferromagnetic substances with examples, the effect of temperature on magnetic properties
Which of the following property shows the property of ferromagnetic substances?
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
Step-by-step solution
Ferromagnetic substances exhibit a strong magnetic behavior that is temperature-dependent. They have a characteristic Curie temperature: below this temperature, they are ferromagnetic; above it, they become paramagnetic. Therefore, option A correctly states the temperature dependence.
