What is Magnet Earth

The magnets that we're most familiar with are made of iron or ceramic.
However, magnets made from rare earth alloys combine different elements to produce what is called a permanent magnet-and these are super strong.
Two of the most common alloys are samarium cobalt and neodymium iron boron. Because the iron in the magnets can rust, they're often coated with gold plate, nickel, zinc, copper, or some combination of those.
How does a rare earth magnet compare to a traditional magnet?
Well, a neodymium iron boron magnet is approximately ten times stronger than the little horseshoe-shaped magnet used in basic science classes.
Magnets are. used in everything from computer hard drives to self-powered flash- lights to wind turbine generators.
