Rare earth magnets were developed in 1966 by K.J. Strnat and G. Hoffer when they discovered an alloy of cobal and yttrium in a laboratory. There are several different types of rare earth metals.

No, rare earth magnets do not stick to gold because gold is non-magnetic. Rare earth magnets are attracted to materials that have magnetic properties, such as iron and steel.
Rare earth magnets, such as neodymium magnets, are much stronger than traditional magnets like ferrite magnets. They are also more expensive and are made with elements from the lanthanide series of the periodic table, making them rarer and harder to produce. Rare earth magnets can retain their magnetization over a longer period of time compared to normal magnets.
A magnet ie. the the ones on your fridge are made by manufactures pushing electrical current through ferrous metals causing them to have magnetic properties. Rare earth magnets are naturally occurring elements that have magnetic properties by themselves.
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.
Rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields. You can make substitutions but you won't get the same strength of magnetism.
Rare earth magnets are very powerful magnets which have no iron. Cobalt and nickel are also magnetic.
Rare earth magnets are made from certain alloys of metals, which produce a very strong permanent magnet. These days there are quite easy to find, with sets available on amazon.com for under $10.
Magnets themselves are not inherently bad for the environment. However, certain types of magnets, such as neodymium magnets, are made from rare earth metals that require environmentally intensive mining practices. Improper disposal of magnets can also lead to environmental contamination.
Iron, Nickel, and Cobalt. Also some of the rare earth metals, like Samarium
what you do is get the two magnets on the edge of a table slightly hang the one you want separated off the edge then get a piece of square wood and puss down and that should do it!
Yes- in the picture above. It is a rare earth mineral, used in magnets and as a color for red or yellow glass.
