Question
Using the concept of magnetic torque, Louis Gouy invented a balance to measure this quantity. For 10 points each:
[10m] Name this quantity symbolized chi calculated by dividing the magnetization by the magnetic field intensity. The Evans balance measures this quantity faster than a Gouy balance, but it tends to be less accurate.
ANSWER: magnetic susceptibility [reject “electric susceptibility”]
[10h] The Fermi surface of a material can be determined using this doubly eponymous effect, which states that as the intensity of the magnetic field increases, magnetic susceptibility tends to oscillate.
ANSWER: de Haas-Van Alphen effect [prompt on partial answers]
[10e] Another form of susceptibility, mass magnetic susceptibility, is inversely proportional to this quantity, which has units of kilogram per cubic meter.
ANSWER: density
