Here's a 'modded' turbo that's said to seperate O2 from air:

NB That the O2 is 'heavier' than the N2 and collected form the periphery of the centrifuge, slightly pressurized.
"There are 3 main benefits resulting from this innovation:
- A drastic reduction in NOx emissions, whatever the test cycle (WLTP, RDE)
- A very significant improvement in cold start emissions, as it is possible to temporarily increase the combustion temperature without creating NOx. (Less particulate emissions)
- A substantial improvement in overall engine efficiency coming from a high EGR rate (No need to pump Nitrogen through the combustion chamber). This also leads to less CO2."

Not a magnetic field in sight and with the expense and complexity of a turbo; why not just turbocharge the engine.
You also have to filter all the dust out of the 'useless' nitrogen before...
Perhaps a properly arranged magnetic field would improve it.
At least it probably doesn't deserve to be in the Unicorn Corral
