The curie temperature is that at which ____________________?
Correct answer: B. Ferromagnetic becomes paramagnetic
- A. Semi-conductor becomes conductors
- B. Ferromagnetic becomes paramagnetic
- C. Paramagnetic becomes diamagnetic
- D. Metals become super conductor
Explanation
At the Curie temperature, thermal agitation destroys the long-range alignment of magnetic domains, changing a ferromagnetic material into a paramagnetic one. Students may choose “paramagnetic becomes diamagnetic,” but the Curie transition specifically removes ferromagnetism.

About Magnetic Flux Density
Magnetic flux density measures the magnetic force acting on a current carrying conductor or moving charge in a magnetic field. Work includes the relations B equals F divided by IL and F equals qvB, the tesla as its SI unit, field direction and the distinction between flux density and magnetic flux.
