magnetic coated wires could improve motor and generator efficiency is a possible new-to-me application of, “the scientists observed a quantum effect revealing the potential to control certain qualities of the metal’s magnetism by spinning electrons
one direction or another.” … “Magnetic damping is responsible for the various qualities of a magnetic field engineers use to turn metal alloys into storage devices, drive magnetic motors, and operate certain kinds of braking devices. “ Noting
that charge flows at the surface of wires, could magnetic coatings, noting magnets have macroscale organized spin, and magnets have the ability to induce particular spins in things near them, cause some improvement to the magnetic effects of wire winding,
like those in electric motors, or power plant generators, or does the really big magnetic field produced at a motor or generator override the effect of a thin coating of supermagnet (like Neoydium Iron Boron) on wire, right at the surface where the
electrons flow? Or, is it a square of the distance thing where the field from the coating is so intense at the top 100 atoms or the like (the especially conductive part) of a wire such that the general magnetic field produced at the motor or generator
winding is actually orders of magnitude lower, being a macroscopic ambience, than that of the magnetic wire coating, and thus the macroscopic motor/generator is less effecting of the spin at the outer layer of the electrical wire, causing magnet coated
wires to have novel beneficial function.

I may have previously written about applying spintronic to catalysts, if not, that could be a technology where the catalyst is at a magnetic field or laser illuminated; I may have even seen an entire university study group that does this.
