Need basic construction details to build storage container with flux shielding for small magnets.

Eric,

Thanks for your very interesting and informative post (#29). I copied that one for future reference !

I tend to be "bulldogish" when setting out to do something. In this case, I just want to mess around with the pipe thing and see what affect it has on a compass compared to magnets in the open air (no containment). Being fully retired, I have extra time and am in no hurry.

That's OK, I am fully retired too, but find magnets (which include electromagnets) so fascinating that I can't leave them alone. People in Greece have their 'worry beads' that they twirl around their fingers. Well, I have 'worry magnets' that I pull apart and click together to relieve stress.

One project that I have is to make a magnet with only one pole. Monopoles should exist naturally, but have never been found. I worked out a way of making one in 1969, but have not yet got around to it as it will not be an easy task, and the years are slipping away. Play while you can.

Eric.

It's called the Meissner effect -> https://en.wikipedia.org/wiki/Meissner_effect

Another cool effect is a free fall of a neodymium magnet inside a copper tube. It takes some time. But eventually it comes out from the bottom side. It would never even get there in a superconducting pipe. Too bad those are so difficult to come by.
