Magnetic Susceptibility and Material Type
The magnetic susceptibility χm of a material is the ratio of its magnetization M to the applied magnetic field strength H. Which statement correctly relates the value of χm to a material’s magnetic properties?
A
χm > 1 for diamagnetic, χm < 0 for paramagnetic
B
χm < 0 for diamagnetic, 0 < χm << 1 for paramagnetic
C
χm is independent of material type
D
χm = 0 for all materials at room temperature
