Above curie temperature

Above curie temperature Correct Answer a ferromagnetic substance becomes paramagnetic

Concept -

  • Ferromagnetic substance -
    • Ferromagnetic materials have a spontaneous net magnetization at the atomic level, even when no external magnetic field is present.
    • They are the materials that, when exposed to a magnetic field, tend to exhibit or display high magnetism in the direction of the field.
    • The alignment patterns of these materials' component atoms are primarily responsible for their magnetic.
    • They are permanent magnets. 
    • Examples: Iron, cobalt, nickel 
  • Paramagnetic substance - 
    • These are metals that have a weak magnetic attraction.
    • The majority of electrons in these substances' atoms spin in the same direction but not all.
    • Examples: Aluminium, Lithium, Magnesium 
  • Diamagnetic substance -
    • Because the electrons in their atoms spin in equal amounts in opposite directions, diamagnetic substances have no observable reaction to the presence of a magnetic field.
    • Diamagnetic materials, to put it simply, are compounds that are usually repelled by a magnetic field.
    • Examples: Gold, Silver, Platinum. 
  • Curie Temperature - 
    • The temperature at which magnetic materials lose their ferromagnetic characteristics is known as the Curie temperature.
    • Simply saying, it is the temperature at which certain materials lose their permanent magnetic characteristics(ferromagnetism) and are replaced by induced magnetism(paramagnetism).
    • Curie temperature is named after Pierre Curie, who discovered that magnetism vanishes at a certain temperature.
    • At the curie temperature, hence, the ferromagnetic material loses its magnetism and becomes paramagnetic. 

Explanation -

  • At and above curie temperature, a substance starts to lose its ferromagnetic property.
  • Thus, the permanent magnet moves toward being a paramagnetic substance.

Hence the correct answer to this question is - above curie temperature a ferromagnetic substance becomes paramagnetic

Find the susceptibility when the curie constant is 0.2 and the difference in critical temperature and paramagnetic curie temperature is 0.01.
If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that
Assertion (A) The ferromagnetic substances do not obey Curie's law.
Reason (R) At Curie point a ferromagnetic substance start behaving as a paramagnetic substance.
