I must be getting old. In my days( now I sound old) magnetic fields had no effect on aluminium

... and then they invented the wheel and the whole world changed!

not magnetic fields, electrostatic maybe. I have no idea what the terms used for this phenomenon are though.

Go back and read it again.
Magnetic fields to remove ferrous waste.
Moving electrical fields to remove aluminium.

Edit: I believe it's called field induction.

That's proof, I am getting old.

Nevertheless....

Aluminum does have magnetic properties, they're just so minimal in comparison to ferrous metals that it's barely noticable.

Yet, you can see that a magnetic field will move an aluminum object by reading this.

Lord, I feel like such a geek right now.

I think the article is saying that a magnetic field is produced in the aluminium ball or cylinder by the generation of eddy currents, not that the aluminium has significant magnetic properties itself.

It is the generation of eddy currents which is important, another example of field induction.

Edit: and on that note, I feel induced to go to bed.

This reminds of those N.A.S.A scientists that created that cannon that shot dead chickens at the windshield of spaceshuttles to test their strength. It was such A neat invention that the Japanese Wanted to borrow it to test it on their new high speed train windshield. So the big day arrived and they all watched in horror as the chicken smashed through their new windshield, snapped the conductor's chair completely in half and then lodged itself in the back wall of the cabin. Well obviously they had no idea what to make of all this so the Japanese scientists packed up all the data and sent it back to N.A.S.A. After long deliberation N.A.S.A. got back to the japanese with this conclusion... THAW THE CHICKEN!

That figures I heard it on the radio it's typical that we would try to put our name on the story instead of being the ones to look stupid. Still A very funny story either way.
