"While it is the geomagnetic storms (GMS) that give rise to the beautiful Northern lights, occasionally they can also pose a serious threat for commercial and military satellite operators, power companies, astronauts, and they can even shorten the life of oil pipelines in Alaska by increasing pipeline corrosion."

Referring to above statement, I would like to know on how geomagnetic storms increase pipeline corrosion.

Does anyone have any suggestions?
Thanks in advance for any suggestions

If I were to hazard a guess, I'd say something like metal pipes are essentially big wires, magnetic fields induce the flow of current through a wire, and since corrosion is an electrochemical process related to the availablility of electrons to flow into out of a material, any external magnetic field can change the oxidation or reduction potential of a metal.

I haven't read these, but I did a quick google search and maybe they'll be relevant.

Apparently, fields can also cause corrision of dental devices. I assume this is the same kind of mechanism.

Corrosion is an electrochemical reaction involving the movement of electrons. Electrochemical reaction requires four elements, all of which must be in contact - the anode, the cathode, the conductive material, and the electrolyte.

Let assume the role of pipe to be anode and cathode at the same time, pipe could mix up with different metals with different galvanic series, so the more active elements become Anode, and the less active elements become Cathode. Would it be corrected? Furthermore, would the stable metal (pipe) generate induced current under the changing magnetic field from geomagnetic storms?

On the other hands, if the electrolyte is the water within the pipe, stable water is water which neither tends to be corrosive nor scale-forming, so stable water cannot be possible to be electrolyte in this case.

Would moving water be the critical factor to be electrolyte? which generate induced current by itself under the changing magnetic field from geomagnetic storms? which become catalyst as an electrolyte.

For Corrosion, do you have any suggestions on whether the moving electrons are generated from stable metal (pipe) or moving water under the changing magnetic field from geomagnetic storms?
Thank you very much for any suggestions :>

Is the claim about pipeline corrosion any real?

Geomagnetic stroms and satellites: don't care.
Power lines: they're protected now, no incident for three decades.

While a geomagnetic storm induces currents in long conductors and electricity relates with corrosion, I doubt very much that the quantity of charges has any perceivable effect. Corroding metal over kilometers length and meters circumference takes huge amounts of current.

You're more likely to observe extra corrosion at pipelines under a power line.

Please see following linked file for details, not the power line, it is pipeline for water.

For Corrosion, does anyone have any suggestions on whether the moving electrons are generated from stable metal (pipe) or moving water under the changing magnetic field from geomagnetic storms?

Thanks, to everyone very much for any suggestions :>

Pipeline corrosion is real, sure, and that's what I've found in the linked document. What I strongly doubt is that geomagnetic storms have any kind of importance to them.
