Question:

A paramagnetic substance is placed in a weak magnetic field and its absolute temperature TT is increased. As a result, its magnetisation

Updated On: Jun 20, 2022
  • increases in proportion to TT
  • decreases in proportion to 1T\frac{1}{T}
  • increases in proportion to T2T^{2}
  • decreases in proportion to 1T2\frac{1}{T^{2}}
