Bookmarked that site for work, always useful to have another supplier for odd bits like that.

In case anyone's wondering how MU metal works. Think of it like copper wires for electricity. The field lines travel easier through the metal than air but you have to have a complete 'circuit' (closed loop around the pole) for it to work well. The thickness, distance, and the magnets field strength all play a part in just how effective shielding is. While I haven't had one like the OP pictured apart I would guess that the actual magnet is much smaller and attached to a soft iron plate at the top.

Retired now, used to run a small frozen dough plant in Desoto, Kansas - we got most of our flour from ADM.

Cool. I work for Siemer Milling Company out of Teutopolis IL. We also have another mill in Hopkinsville Ky. They send us to Manhattan Kansas for milling courses every once in awhile.

Yeah, we had those magnets in our pneumatic conveying tubes, they were so powerful they'd pull the iron out of the flour.....as in iron enrichment, not nuts and bolts.

Is that the difference in "enriched flour" and "Plain flour"?

Oh sure, AIB, been there many times for different courses.

And to the question about enrichment, it's one of the things that's added, but not the only one.

It was just interesting to me to pull the magnets after we got a load of flour and and see the iron ore "fuzz" around the edges of the magnet....

One is magnetic, the other isn't ;)

& while we're talking magnets.... Kaiser Steel has had some dubious quality ALUMINUM that was magnetic.. I'm not talking about Dysprosium-Erbium-Aluminum alloy either..

Used to work for one of the major world producers of aluminum. We actually had some that would rust - red rust. Hmmmm, wonder what that was.

Unobtanium is a primary component in British cars. A guy I worked with was assembling a magnetron sputtering source, he got the magnet bars too close together and they pinched his fingers. We had to drive a wooden wedge between the bars to separate them. Four guys couldn't pull them apart.

It looks like it was used in food processing just like some of you said. WHAT'S IT WORTH!

Magnetron magnets are fun things to put in your desk and watch people's pens, key chains, various metallic objects shoot across the surface....

Had one when I was in the Air Force...put it in the drawer (wooden desk)...confused many folks...

As a Brit car owner I'm qualified to state that they are made from iron oxide.


I've had several credit cards over the years... had the platinum card, then there was the titanium card. After seeing my bills the wife told the credit card company to send me an unobtanium card.

Isn't unobtanium the stuff that Lucas electronics makes to use in English refrigerators so that their beer stays warm?
