corrosion due to magnetic field?
(OP)
i have an electric motor that's submerged in water/glycol. after 1000 hrs of testing, i noticed two regions of corrosion or pitting 180 degrees from eachother. the corrion only effects the ends of the magnetic region of the rotor (see attached sketch). does anyone know what may have caused this? my guess is that it was caused by the magnetic field but i was hoping someone could help me understant the physics or chemistry behind it.
rotor material: inconel 625
motor power: 1.8 MW

RE: corrosion due to magnetic field?
If there is a voltage it is possible that you created conditions for galvanic corrosion.

It is possible to have slow corrosion rate due to magnetic field based on the material , electrolyte, electrodes.
