How To Demagnetize Steel Pipe

[Pollack]

Do you know how to demagnetize steel pipe? Also, is it true that it can actually magnetize just from sitting on the ground for an extended amount of time?

Are you welding? I think you can demagnetize the pipe with a commercial product (degausser) or by heating it to its Curie temperature. The latter will be impossible to do without a furnace. I remember doing a science experiment as a kid where we used a hammer to demagnetize a steel pipe, but I don't remember the steps.

I think the hammer trick may work. Hit it hard with a hammer....really.
