Finding the magnetization vector and magnetic field?

  1. Nov 25, 2014 #1
    I've been stuck on this question for a few hours and I hope someone can help. Here is the question:
    "Consider two materials bismuth and aluminum with χ m = −20 ×10−5 and
    χ m = 2 ×10−5, respectively. Find the magnetization vector and the magnetic field
    in these materials when they are under an external magnetic field of 1 T in
    direction x."

    SO far what I have is this: magnetic susceptibility is defined by Xm= M/H = ur-1, and then M= (sigma Um)/ Volume. However, I am not sure where to go from here..
