I'm currently trying to develop a system to remove some 5140 steel
chips off the part magnetically. I know the part weighs about 9.4 lbs
and I'd need to remove about a hand full of chips per part. The
cycle time is about 1min 30secs, so the volume is not that great. I
cannot use a magnetic conveyor; it has to be some type of rotating
magnetic assembly over the top of the part that can clear the chips by
itself some how. I was just wondering if anybody has any ideas or if
you have a similar situation? Maybe someone out there sells something
I could use?? Any help is appreciated.
Thanks.

I vaguely recall something in one of the "science" hobby magazines
from about 40 years ago (Popular Science?) about making a very
strong electromagnet with a wound AC primary and a very high
current secondary made from Silver washers. IIRC You melted down
Silver dollars to make the washers ... or drilled holes in them ...
A spare M code could power the primary on & off I suppose ...
