Magnetic susceptibility: It is defined as the intensity of magnetisation per unit magnetising field, 

i.e. zm = M/H. It has no unit. 

Iron has positive susceptibility while copper has negative susceptibility. Negative susceptibility of a substance signifies that the substance will be repelled by a strong magnet or opposite feeble magnetism induced in the substance.
