Curie temperature is the temperature above which

ferromagnetic material becomes paramagnetic material

paramagnetic material becomes diamagnetic material

paramagnetic material becomes ferromagnetic material

ferromagentic material becomes diamagnetic material

Solution

ferromagnetic material becomes paramagnetic material

Ferromagnetism decreases with rising in temperature. If we heat a ferromagnetic substance. If we heat a ferromagnetic substance, then at a definite temperature the ferromagnetic property of the substance suddenly disappears and the substance becomes paramagnetic.The temperature above which a ferromagnetic substance becomes paramagnetic is called the Curie temperature of the substance.

Answer the following question regarding earth:
Geologists claim that besides the main magnetic N-S poles, there are several local poles on the earth's surface oriented in different directions. How is such a thing possible at all?

Answer the following question:
The earth's magnetic field varies from point to point in space. Does it also change with time? If so, on what time scale does it change appreciably?

Answer the following question:
The earth's core is known to contain iron. Yet geologists do not regard this as a source of the earth's magnetism. Why?

Answer the following question:
The charged currents in the outer conducting regions of the earth's core are thought to be responsible for earth's magnetism. What might be the ‘battery’ (i.e., the source of energy) to sustain these currents?

Answer the following question:
The earth may have even reversed the direction of its field several times during its history of 4 to 5 billion years. How can geologists know about the earth's field in such distant past?

Answer the following question:
The earth’s field departs from its dipole shape substantially at large distances (greater than about 30,000 km). What agencies may be responsible for this distortion?
