Magnetism may interact with the Earth’s natural magnetic field, however, today’s magnets are not formed naturally. One of the only naturally occurring magnets is lodestone, but it’s magnet strength is too weak for use in practical applications. Modern magnets are much stronger, because they are created from alloys of ferromagnetic metals, which include: iron, nickel, cobalt and a few others. Ferromagnetism actually means the ability for certain materials to be magnetic or magnetized.

These ferromagnetic metals form alloys that then become the different types of permanent magnets. Four of the most common permanent magnets are:
Neodymium (NdFeB:neodymium-iron-boron)
Samarium-Cobalt (SmCo)
Alnicos (aluminum-nickel-cobalt)
The magnet-making process may vary slightly depending on the type of permanent magnet. Neodymium magnets are the most common and generally strongest of the types, so for this blog, let’s focus on how they are made.
