Question
The Aharonov–Bohm, or AB, effect shows the physicality of these functions. For 10 points each:
[10h] Name these two functions that are combined into a four-vector denoted “A-super-alpha.” The negative gradient and curl of these functions respectively give the E- and B-fields. You can give the word shared by their names.
ANSWER: electromagnetic potentials [or electromagnetic four-potential; accept electric scalar potential or magnetic vector potential]
[10m] The AB effect was first observed with these devices that generate uniform magnetic fields described by the equation, “B equals mu-nought N I over L.”
ANSWER: solenoids [prompt on electromagnets or coils or wires]
[10e] Solenoid-shaped Dirac strings, which connect these objects, may carry out the AB effect. Gauss’s law for magnetism forbids these objects that feature only a “north” or “south” end.
ANSWER: magnetic monopoles [or Dirac monopoles]
