because they find each other very attractive
No, gold is not magnetic and does not attract magnets. It is a non-magnetic metal, which means it does not have magnetic properties.
It depends on the composition of the metal plate. Magnetic materials like iron or cobalt would make the metal plate magnetic and attract a magnet. However, non-magnetic metals like titanium or stainless steel would not attract a magnet.
The strong magnet is attracted to the door magnet because opposite poles attract each other - the door magnet was likely oriented to attract the strong magnet. The metal thumbtacks are not attracted to the strong magnet because the magnetism of the thumbtacks is weaker compared to the door magnet.
If it is a magnet, then it can still attract to a refrigerator. If it is a lump of hot metal or hot ceramic, then only gravity will provide attraction. The curie temperature describes when it goes from being a magnet to being a lump.
It depends on the material the key is made of. If the key is made of a ferromagnetic material, such as iron, then yes, a magnet will attract it. If the key is made of a non-magnetic material, such as aluminum or brass, then the magnet will not attract it.
Metal?
Metal?
The exact same way that a normal magnet attracts metal.
Yes.

There are magnets in magnets that magnetically attract metal...
magnets only attract iron and steel
anything that contains metal, or the opposite polar attraction for the magnet (i.e. the + will attract to the - and vice versa)
No, gold is not magnetic and does not attract magnets. It is a non-magnetic metal, which means it does not have magnetic properties.
yes
No. Aluminum is a non-magnetic metal.
No, aluminum is a non ferrous metal.
