what is the Field strength in Gauss?

What jewelry metals are magnetic? Thanks

The magnet should always be the first test you perform on an unknown piece of jewelry. If there is any steel or iron present, the magnet will attract. These metals are common in costume jewelry where they are electroplated with gold or silver, but they will never be present in high quality jewelry (with the possible exception of clasps, which sometimes have steel springs inside them). It is important to note, however, that not all fake jewelry will have these metals present because there are other non-magnetic metals that can be used as a base. A deliberate forgery might have metals such as brass or tungsten as a base metal, and these are non-magnetic just like gold and silver. Anything that passes a magnet test (no reaction from the magnet) can be scrutinized further.

Can this use to distinguish silver and nickel?

Yes, silver will not stick to a magnet whereas nickel will.

Can it be used on coins?

Yes that’s why I bought one. Works well when checking silver coins/jewelry at estate and garage sales.
