When a ferromagnetic material is heated to 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
When a ferromagnetic material in heated above its curie temperature then it behaves like paramagnetic material.These are metals that are weakly attracted to magnets. They include aluminum, gold, and copper. The atoms of these substances contain electrons most of which spin in the same direction but not all. This gives the atoms some polarity.

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.
