Data from wikipedia needs some care. Many times the information posted on Wiki is not moderated - so a double check is always good.

  According to Wikipedia[1] (or somewhere else, but everyone has Wikipedia  :-) ), 
  the magnetic permeability is the volumetric susceptability plus one

  \mu_r = \chi_m + 1

  \chi_m can be found from the link, I sent the last time[2], but the value is

  \chi_m = -3.73E-6
