Electrons moved with higher energies show an unexpected tilt.

Electrons travel, as if on a highway, in different directions, with their axis of spin aligned differently according to the direction of travel.

In addition to demonstrating this novel method and showing its effectiveness, Gedik says, “we learned something that was not expected.” They found that instead of the spin being precisely aligned perpendicular to the direction of the electrons’ motion, when the electrons moved with higher energies there was an unexpected tilt, a sort of warping of the expected alignment. Understanding that distortion “will be important when these materials are used in new technologies,” Gedik says.

There must be a way to exploit this phenomena. My question is how does this affect the magnetic field of a current with large impulse or a large but quickly changing current? Is this what causes an external magnetic field in the first place?
