Permanent magnets are those that can provide a magnetic flux without the need for electricity, as is the case with electromagnets.
They are made from ferromagnetic materials, which, after being magnetized, retain these magnetic properties for an indeterminate time, that is, until they are demagnetized.
From the material with which they are made we can define the types of permanent magnets:
Neodymium Magnets
Ferrite Magnets
Samarium Magnets
Alnico Magnets
