Question
Crossing this quantity with the B-field gives torque. For 10 points each:
[10h] Name this quantity that describes the strength and orientation of a magnetic field. This quantity equals current times enclosed area for a loop of current.
ANSWER: magnetic moment [or magnetic dipole moment; prompt on dipole moment; reject “electric dipole moment”; reject “magnetic flux”]
[10e] The intrinsic magnetic moment of an electron is approximately one times this physicist’s namesake magneton. Electrons orbit a positive nucleus in this Danish physicist’s model of the atom.
ANSWER: Niels Bohr [or Niels Henrik David Bohr; accept Bohr magneton or Bohr model]
[10m] A type of this phenomenon named after Joseph Larmor is caused by a magnetic moment in an external magnetic field. The gyroscopic form of this phenomenon is torque induced.
ANSWER: precession [accept Larmor precession; gyroscopic precession or torque-induced precession]
