</div>It may have fallen over aligned North to South. That is one way to magnetize iron things, although the effective is usually small. More likely not was a faulty magna flux job. I mention it only to suggest you check for damage/bending when you get it demagnetized which is a good idea.

I would think that a shop that does magneflux should be able to de-mag it. As you noted that’s probably how it got magnetized.

Alternately line the crankcase with a couple of copper wire coils and make it serve as a generator. 😎

<span style="font-family: helvetica; font-size: 12pt;" class="">I discovered that one of the spare TR crankshafts I have is magnetized. I acquired it years ago. It has a fresh 10/10 regrind and it is a candidate for friend's rebuild. I was knocking it's damaged flywheel dowel pin out when I noticed the drift stuck to the flange. Can anyone shed some light on this? The crank is being sent to a shop for cleaning, crack check and full inspection. Perhaps the crank had been "magna"fluxed and not properly demagnetized afterward. I don't think a magnetized crank would be good to use. It would attract particles. </span>
