Iron and Nickel are two of them. You can say steel since it is mostly made of iron.
The easiest way to check for steel is to use a magnet. A magnet is going to pick up steel and will not pick up metals that do not contain iron.
A magnet will not pick up non-ferrous metals such as aluminum, copper, gold, or silver as they are not magnetic. Additionally, stainless steel, which contains a higher proportion of chromium and nickel, is typically not magnetic and will not be picked up by a magnet.
No, platinum and gold are not magnetic, so they cannot be picked up by a magnet. They are both precious metals that have different properties than magnetic materials.
No metals can attract a magnet. Only magnets can attract metals. (Believe me there is a difference). However the most common examples of metals which magnets would be able to pick up are Iron and Steel (steel is an alloy of Iron and Carbon)
The number of paperclips a bar magnet can pick up will depend on the strength of the magnet and the size of the paperclips. In general, a typical bar magnet can pick up several small paperclips at once.
Magnets only pick up ferromagnetic materials. There are many metals that a magnet will not pick up. A magnet will pick up an iron nail but will not pick up a piece of copper wire. Magnets will only pick up Nickel, Cobalt, Iron, and Steel, if I remember my middle school science correctly.
metals containing iron
Metals + Stone = Magnet
Yes - if you have a powerful enough magnet !
No
It will pick up the nails the same way a bar magnet would do!
A real one can't, it's made from 90% silver and 10% copper and are not magnetic.
