what are magnets made of?

Question

what metals? i need to do an experiment involving iron and my brother told about an expriment that showed something about iron and magnets.

Answer 1

atoms...just like everything else!

Answer 2

There are many different ways to make magnets, dependant on whether you wish to make an electromagnet of say a permanent magnet.

1 patent for the alloy preparation (United States Patent 4382061) has the has the rights to:

The production of permanent magnets based on a cobalt/rare earth metal alloy in the atomic ratio of 5:1 to 7:2, where the rare earth metal component is composed of about 40 to 60 atomic percent of samarium, about 15 to 30 atomic percent of lanthanum, about 15 to 30 atomic percent of neodymium, and the remainder that is a content of other rare earth metals resulting from preparation

....but there are many types like:
Alnico Magnets
Ceramic Magnets
Compression Bonded Neodymium
Injection Molded Neodymium and Ferrite
Samarium Cobalt
Sintered Neodymium

Answer 3

What is a lode stone?

its a magnetic rock they were used on ancient ships to help navigate.Its a piece of magnetite that has magnetic properties. These were the first magnets.

Modern magnets are made up of different metal combinations. ALNiCo magnets are an example.
When i was a kid i made a contraption that made iron objects magnetic, Basically a coil of thin wire around a paper tube. a quick burst of electricity as used . The domains in the metal were lined up in one direction and as a result a magnet was formed.

Answer 4

They contain iron in some form or another.

The iron could be purified into steel (always popular in magnets).
It could be iron ore like magnetite
It could be iron powder embedded in flexible plastic (often seen in refrigerator door gaskets)
It could be steel mixed with vanadium to make a particularly retentive form of magnet ("alnico")

After the iron containing item is in the desired shape it is typically subjected to a strong magnetic field that organizes it into a permanent magnet for actual use.

Answer 5

Little furry creatures that are very attracted to each other, but only to opposite sides...

Seriously, read up. There are several metals, particularly alloys, that make good magnets - Iron is just one. The holy grail of that branch of physics is to find the right combination of materials to create room temperature superconductors...

Answer 6

It seems like the most common materials are Iron, Cobalt, Nickel. But there are alot - read more here:
