Is it possible to do absolute magnetic field (flux) measurements using a SQUID?

Hey mate ^_^
You can count the periods. In practice it would probably be a good idea to have two devices that are being kept 90 degrees out of phase to make sure that one doesn't skip any of the periods...

Hello mate here is your answer.
Well, the flux is defined that way, isn't it ? From the definition Φ=∬B⋅dS=∮A⋅dlΦ=∬B⋅dS=∮A⋅dl, ΦΦ flux, SS-surface, BB-magnetic induction, AA-vector potential, ll-path-element. You may see a gauge transform as a change of the reference. I know it's puzzling because you believe a gauge transform does not affect the integrals hence the flux ΦΦ, but in fact it's the same as the problem of absolute voltage: you can only measure a voltage drop because E=−∇VE=−∇V up to a gauge transform. What I meant by that is that, if B=∇×AB=∇×A, then BB .
Hope it helps you.
