AFAIK,the CRT shield should not be magnetic.
Are you sure your blade is not magnetized?

you're right, I picked a magnetized blade :(
I checked with another one and this time I couldn't find any
magnetization on the shield.
So problem "solved".


try a TV degaussing coil to remove the magnetism from the shield.

it has none, as far as I can tell at least. I read that a mu-metal
shield shouldn't magnetize at all.

Thanks for hint and best regards

TEK used to glue tiny magnets on their CRT necks and bells to center the
beam,I've seen a few that had come off and stuck to the inside of the
shield.the magnets were about 2mm in diameter and 2mm high.
