A ferromagnetic material is heated above its curie temperature. Which one is a correct statement

Explanation

When a ferromagnetic material is heated above its Curie temperature, the thermal energy overcomes the magnetic energy that keeps the domains aligned. Consequently, the domains become randomly oriented, and the material loses its ferromagnetic properties, becoming paramagnetic instead. Option B is correct because it accurately describes this transition. Option A is incorrect because the domains are not perfectly arranged; they become disordered. Option C is incorrect because the domains are affected by heating. Option D is incorrect because the material becomes paramagnetic, not diamagnetic.
