Question

What is Curie point of a magnet?

Answer 1

1. Curie point is a temperature at which magnetic materials pass through a change in their magnetic properties.
2. This temperature is called Curie point or the Curie temperature.
3. The mathematical relation for Curie point
   $\mathrm{\chi }=\frac{\mathrm{C}}{\left(\mathrm{T}-{\mathrm{T}}_{\mathrm{C}}\right)}$
   where,$\mathrm{\chi }$ represents magnetic susceptibility, $\mathrm{C}$ represents material specific Curie constant, $\mathrm{T}$ represents absolute temperature and ${\mathrm{T}}_{\mathrm{C}}$represents Curie temperature.
4. At Curie temperature ferromagnetic materials behave like paramagnetic material.
