Question

Find the correct combination regarding relative permeability and magnetic susceptibility of a paramagnetic substance.

Easy
Solution

The correct combination for paramagnetic substances is given as follows:
μr > 1, χ > 0
Paramagnetic materials have a small and positive value of magnetic susceptibility (χ). The relative permeability (μr) of paramagnetic materials is just greater than 1.
