# Explain curie law in details

Pierre curie experimentally found that magnetization of a paramagnetic sample is directly proportional to the magnitude of applied external magnetic field $left( {{overrightarrow{B}}_{ext}} right)$ and inversely proportional to Temperature (T)

$Mpropto {{overrightarrow{B}}_{ext}}$ $Mpropto frac{1}{T}$ $M=Cfrac{{{overrightarrow{B}}_{ext}}}{T}…(1)$

This is known as curie’s law

C – is curie constant

${{overrightarrow{B}}_{ext}}$ – is applied external field

T – Temperature
