Details
Silver is not magnetic. However it is 'diamagnetic' - a sliding magnet sets up an 'electrical field' which you can detect with suitable magnets.
These magnets are 'suitable' because of their size and power, read all about it.
Sizes:
3 X 1mm, neodymium
7 X 4mm, neodymium
10 X 2mm, neodymium
20 X 5 X 2mm, neodymium
8 X 4mm, iron
IMPORTANT
Copper reacts the same way as silver (though the effect isn't as strong), so this test will not tell you if you have a copper coin plated with silver. YOU STILL NEED A SILVER TESTER to be certain.
