For 10 points, name this value symbolized chi, which gives the amount of magnetization that an object obtains when placed in a magnetic field.
A device used to measure this quantity is calibrated using mercury cobalt thiocyanate, whose value for this parameter is 16.44 times 10 to the minus 6; that device is an Evans balance. Objects which are anisotropic in this quantity are described using the Nye ellipsoid. For certain materials it is equal to the Curie constant over the difference between temperature and the Curie temperature. This parameter is equal to one minus the permeability, and its sign tells whether an object is paramagnetic or diamagnetic. This value times the H-field gives the magnetic dipole moment per unit volume.
