Curie temperature is the temperature above which

CONCEPT:

• Curie temperature: Curie temperature is the temperature at which the magnetic properties of a material change. At this temperature, the magnetic materials lose their magnetic property.
  • When the temperature is greater than the Curie temperature, ferromagnetic material becomes paramagnetic material.

• Diamagnetic Substance: Diamagnetic substances are those which develop feeble magnetization in the opposite direction of the magnetizing field.

• Paramagnetic substances: Paramagnetic substances are those which develop feeble magnetization in the direction of the magnetizing field.

• Ferromagnetic substances: Ferromagnetic substances are those which develop strong magnetization in the direction of the magnetizing field.

EXPLANATION:

• The minimum temperature at which a ferromagnetic substance is converted into a paramagnetic substance is defined as Curie temperature.
• At this temperature, the ferromagnetism of the substances suddenly vanishes.
