In paramagnetic materials, the external magnetic field $$\boldsymbol{B}$$ is amplified by the magnetization $$\boldsymbol{M}$$ of the material, so that the internal magnetic field $$\boldsymbol{B}_{\text i}$$, i.e. the magnetic field within the material is greater:$$\boldsymbol{B}_{\text i} = \boldsymbol{B} + \mu_0 \, \boldsymbol{M}$$

The magnetic susceptibility $$\chi$$ is positive in the case of paramagnetism:$$\boldsymbol{B}_{\text i} = \boldsymbol{B} + \chi \, \boldsymbol{B}$$
