Question

how do i find the magnetic susceptibility of a material in relation to it's permittivity and permeability?

Answer 1

magnetic field of any materials depend on its permeability...
permeability of the materials can be determined by \[\epsilon\] . k = \[\epsilon' \]

Answer 2

Don't worry, found it.

FYI: \[X _{b} = (1-\mu _{r})^{-1}\] where \[\mu _{r}\] is the relative permeability

Answer 3

right
