magnetic susceptibility - 2024 Penn Bowl Florida

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
