When a ferromagnetic material is heated above the curie temperature, it becomes:
  • a)
    paramagnetic material
  • b)
    non-magnetic material
  • c)
    diamagnetic material
  • d)
    strongly charged
Correct answer is option 'A'. Can you explain this answer?

When ferromagnetic material heated beyond curie temperature,  turns into paramagnetic material, as the ferromagnetic domains become random.
Curie temperature:
Curie temperature is the temperature at which the magnetic properties of a material change.
When the temperature is greater than the Curie temperature, ferromagnetic material becomes paramagnetic material. Here, X as (magnetic susceptibility) vs. T (temperature)

Additional Information
Ferromagnetism:
Ferromagnetism is the presence of magnetic domains which are aligned in the same direction in magnetic materials. The most common examples of ferromagnetic materials are metals such as iron, nickel, cobalt, and metal alloys.

Antiferromagnetism:
  • Antiferromagnetism is the presence of magnetic domains that are aligned in opposite directions in magnetic materials.
  • These opposite magnetic domains have equal magnetic moments which are canceled out (since they are in opposite directions).
  • This makes the net moment of material zero. This type of material is known as antiferromagnetic materials.
