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.
What else can I help you with?
How are rare earth magnets different to normal magnets?
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.
Where can you get rare earth magnets?

Will a Rare earth magnet stick to gold?
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.
Who invented the Rare Earth Magnets?
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.
What is the difference between a magnet and a rare earth magnet?
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.
What are some names of small magnets?
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.
What can you use instead of a rare earth magnet?
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.
If an element has no iron will it be magnetic?
Rare earth magnets are very powerful magnets which have no iron. Cobalt and nickel are also magnetic.
What is inside magnets?
There is nothing inside magnets. The solid metal has magnetic properties due to it's molecular make up. Magnets are commonly made of iron, but there are more powerful magnets, made from alloys of rare earth metals. The magnetic fiels surround the whole magnetic object.
What is the melting point of neodymium?
The rare earth metal neodymium melts at 1024 °C, or 1875 °F, or 1297 K. Use the link below to learn more about the metal that, when alloyed with iron and a hint of boron, makes the strongest known permanent magnets.
Are magnets bad for te envirment?
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.
What are the only metals that can be magnets?
Iron, Nickel, and Cobalt. Also some of the rare earth metals, like Samarium
