The correct order of Magnetic susceptibility of Paramagnetic (χMP), diamagnetic (χMD), ferromagnetic (χMF) materials is Correct Answer χ<sub>MF</sub> &gt; χ<sub>MP</sub> &gt; χ<sub>MD</sub>

Paramagnetic Materials: The Magnetic field in the material is strengthened by the induced magnetization. Magnetic susceptibility is a small positive

Diamagnetic Materials: The Magnetic field in the material is weakened by the induced magnetization. Magnetic susceptibility is a small negative

Ferromagnetic Materials: Ferromagnetic materials possess permanent magnetization even without an external magnetic field. Hence these materials have a large positive value of magnetic susceptibility.
