Hi Ulysse21 and Bacardi,
I bought mine on Amazon. They are 1/8" x 1/2" circular. If you experiment with them on the outside of equipment near transformers and on AC adapters you may get good results. There is another audio site that has a lot of posts about using magnets to mitigate the effects of EMFs. I cannot name this site because this post may not make it to the forum if I do.
