What metals will a magnet pick up?
Ferromagnetic metals are strongly attracted by a magnetic force. The common ferromagnetic metals include iron, nickel, cobalt, gadolinium, dysprosium and alloys such as steel that also contain specific ferromagnetic metals such as iron or nickel.
Will 10 karat gold stick to a magnet?
Gold is a non-ferrous metal, which means it won’t attract the magnet. So, even if the item is slightly magnetic, but doesn’t stick to the magnet, then it’s gold-plated.
Can you pick up platinum with a magnet?
The only ferromagnetic metals (those that are attracted to a magnet) are iron, nickel and cobalt, and some of there alloys. Platinum doesn’t stick to a magnet.
Will a magnet stick to copper?
The Issue about Strong and Weak Metals In their natural states, metals such as brass, copper, gold and silver will not attract magnets. … Magnets only attach themselves to strong metals such as iron and cobalt and that is why not all types of metals can make magnets stick to them.
Can a magnet pick up silver?
Silver isn’t noticeably magnetic. In fact, only iron, nickel, cobalt, gadolinium, neodymium and samarium are magnetic in our everyday lives. … An ingot of pure silver isn’t attracted to a magnet.
How do you test for real silver?
The Ice Test Cheap and easy to do, getting some ice from the freezer is a simple way to test both silver coins and bars for authenticity. All you need to do is place the ice on the silver and watch.

What kind of magnet attracts gold?
The trick is to make a magnet that will attract gold but not magnetite. It might need to be some kind of A.C electromagnet. The gold particle should be classified as a closed circuit inductance. The gold particle will be resonant at a certain frequency.
