Magnetic permeability  μ  =      B    H  Where, B=magnetic flux density=0.63 TH=intensity of magnetic field   =  5  ×      10    5        A    m    μ  =            0.63             T              5      ×              10        5                           A        m              =  0.126  ×      10          −      5           N      A          −      2      Find magnetic susceptibility   χ:  B  =  μ  H  (  1  +  χ  )    χ  =      B          μ      H        −  1    =            0.63             T              5      ×              10        5                   A              m                  −          1                    ×      0.126      ×              10                  −          5                           H              m                  −          1                      −  1    =  0Magnetic susceptibility explains how the spins in a material will align themselves when magnetized.If material aligns in the direction of applied magnetic field,   χ  &amp;gt;  0, the material is paramagnetic.If material aligns against the direction of applied magnetic field,   χ  &amp;lt;  0, the material is diamagnetic.In this problem,   χ  =  0 implies the material do not respond to the applied magnetic field. Thus the material is neither paramagnetic nor diamagnetic in nature.Or the material might be a very weak paramagnetic or very weak diamagnetic in nature (because its susceptibility might be approaching zero).
