Fig 13.49.Toy model for the quantum spin Hall effect. (a) Two copies of the IQHE with opposite magnetic fields. In each copy, time reversal is violated due to the external magnetic field, and the edge state has a definite orientation (hence, it is a chiral edge state).

Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics.
Join them; it only takes a minute: I am somewhat confused about this topic.
But what about the moment associated with the electron spin?
Is the spin of an electron not an intrinsic property?
So why if indeed it does would running time backwards change the sign of the spin?
EDIT: I appreciate all of your comments below, but I feel this question has got away from me somewhat.
I should have added more information at first.
I am wondering about Anderson's description of a dirty superconductor where the pairing is between so-called time-reversed states.
In Tinkham it says that these states are only degenerate in the absence of magnetic or other time-reversal noninvariant terms.
This makes the previous edit now in italics a little confusing to me.
Back to the loop of current: Surely if you switch the charge and the direction of flow then the magnetic field stays pointing in the same direction.
Where is the inconsistency here?
Charge is an invariant under so electrons stay electronsand to make out of a electron travelling forward in time time reversal spin magnetic positron going backward in time we would have to apply at least the combined CT-symmetry, if not the whole CPT.
I meant that an time reversal spin magnetic travelling backwards in time looks like a positron.
After all, the photons involved would need to reverse direction also, traveling from our retinas to the viewed objects.
Bottom line, classical time doesn't reverse well, regardless of how well time reversal at the particle level works.
The notion time reversal spin magnetic "antimatter is game best vegas betting in going backwards" arises from CPT being a symmetry of every conceivable theory, so that antimatter going backwards i.
An "up" electron spin state simply becomes a "down" spin state.
Electron spin remains fundamentally a type of angular momentum, even though the rules get a bit odder betting nfl draft the quantum scale.
Incidentally, when time is reversed all particles also turn into their antimatter equivalents.
So a bit of safety advise: Never, ever shake hands with the other you that you see in a reverse video.

It is usually explained how magnetic fields avoid break*ing* time reversal symmetry by the example of a field produced by a circulating charge current - run time backwards, the current direction is reversed and so is the field. But what about the moment associated with the electron spin? Is the spin of an electron not an intrinsic property?

However, if the magnetic field gets substantially weaker and stays that way for an appreciable amount of time Earth will be less protected from the oodles of high-energy particles that are.

Time reversal (T) For spin/boson systems, time reversal acts on physical states in a simple way. In particular T2 = + 1 on all physical states. Contrast with electronic systems where T2 = -1 and there is a Kramers degeneracy.

what time reversal is, and why one should care about it. Section 3 is a critical review of the existing debate concerning time reversal in classical electromagnetism: the standard ‘textbook’ account, Albert’s objection, and Malament’s reply. In section 4 we articulate the ‘Feyn-man’ account.

With time reversal, the spin would appear to reverse, like a movie of the particle played backward. But for the equations to balance, the EDM would have to equal zero.

time reversal, and we find that electromagnetic effects are overall time-reversal invariant. We have shown this only in classical mechanics, but it is also true in quantum mechanics. Similarly, in quantum physics we are often interested in the time-reversal invariance of a given system, such as an atom interacting with external fields.

With time reversal, the spin would appear to reverse, like a movie of the particle played backward. But for the equations to balance, the EDM would have to equal zero. Any non-zero value would generate a different outcome of the equations – the backward version of the movie actually would be different from the forward version.

This book introduces new developments in the field of Time-Reversal Symmetry presenting, for the first time, the Wigner time-reversal operator in the form of a product of two- or three time-reversal operators of lower symmetry. The action of these operators leads to the sign change of only one or two angular momentum components, not of all of them.
