Here s how we do it in our onsite manufacturing plant. There is a group of materials known as ferromagnetic materials.

We break it down to build it back up.

Permanent magnet can be made from. In the 1970s researchers developed permanent magnets made from powdered samarium cobalt fused under heat. Ceramic ferrite samarium cobalt smco and neodymium iron boron neo magnets are all made through a process called powder metallurgy. The rest of the magnets we see today are created manmade.

This group includes iron cobalt nickel and some alloys of rare earth elements mainly neodymium and samarium. Permanent magnets are made from hard ferromagnetic materials such as alnico and ferrite that are subjected to special processing in a strong magnetic field during manufacture to align their internal microcrystalline structure making them very hard to demagnetize. Flexible permanent magnets are made from powdered barium ferrite or strontium ferrite mixed in a binding material like rubber or a flexible plastic like polyvinyl chloride.

How are permanent magnets made. These ferromagnetic materials can be made magnetic by exposing them to a magnetic field using electric current.
