Then it is not fully efficient as a diamagnetic material.
You will note that the SS retains energy in its magnetic
condition via a hysteresis curve.

This all got me wondering ...

Just walked out to garage, with a neodymium magnet, where I have some 8+
ft whips stuck up overhead. Only one of them had NO attraction to the
magnet at all. I believe it is an old antenna specialists ChickenBand whip!

Apparently, back in the 70's the SS in the whips was better. However, I
think the military ones contain the iron for strength, they are tough.
