CONCEPT:

Ferromagnetic materials:

  • In some materials, the permanent atomic magnetic moments have a strong tendency to align themselves even without any external field.
  • These materials are called ferromagnetic materials.
  • In every unmagnetized ferromagnetic material, the atoms form domains inside the material.
  • Different domains, however, have different directions of magnetic moment and hence the materials remain unmagnetized.
  • On applying an external magnetic field, these domains rotate and align in the direction of the magnetic field.

EXPLANATION:

  • Beyond curie temperatureferromagnetic material turns into paramagnetic material, as if ferromagnetic domains become random. Therefore option 1 is correct.
