Heating of ferromagnetic materials to a temperature above Curie temperature makes it ________________________?
Correct answer: C. Behave like paramagnetic materials
- A. Insulator for heat & electricity transmission
- B. Ferritic
- C. Behave like paramagnetic materials
- D. Superconductor
Explanation
Above the Curie temperature, ferromagnetic domain alignment is lost and the material exhibits paramagnetic behaviour. It does not become ferritic or superconducting merely because it is heated past this temperature.
