Re: A little experiment on demagnetization

Hello,

There have been HUGE improvements in magnets over the recent years...

And when you buy used, or surplus, you may be buying anywhere along
this technology curve...

Also, improvements in mfg. make tighter tolerances possible, again
reflected in output vs. size.

Hope this helps,

Ballendo
