GD&T of magnets

GD&T of magnets

(OP)
Can anyone tell me the proper way to GD&T magnets with their orientation, polarization, etc., or where I might be able to track down such information?  Thanks!!

RE: GD&T of magnets

Just do GD&T on the physical part. There isn't GD&T for orientation and polarization. You may need a note for grain direction, depending on the material.

RE: GD&T of magnets

Fred,

As Chris mentioned, I do not believe there is symbology for magnetism in mechanical drafting, but there may be some in electrical drafting.  Don't a bried yahoo search, I found this link that may point you in the right direction:

http://www.bnl.gov/magnets/magnet_files/Publications/MDN-609-20.pdf

It's dealing with electro-magnets, but may have some clues to answer your question.
