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.

QUESTIONS & ANSWERS

Ask a Question
  • Is this a strong magnet?

    This is a set of magnets, they are neodymium, they are the strongest for the size. They are not large – large magnets would not work for this purpose.
