When a ferromagnetic material is heated to a temperature above its Curie temperature, the material:
Correct answer: D. Behaves like a paramagnetic material
- A. Is permanently magnetized
- B. Remains ferromagnetic
- C. Behaves like a diamagnetic material
- D. Behaves like a paramagnetic material
Explanation
Above the Curie temperature, the thermal energy is sufficient to overcome the magnetic alignment within the domains of a ferromagnetic material. This disrupts the long range order, causing the material to lose its strong magnetic properties and behave like a paramagnetic substance.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
