The type of magnets

Magnets are permanent in the sense that once they have been magnetized they retain a certain degree of magnetism. Permanent magnets are generally made of ferromagnetic material. Such material consists of atoms and molecules that each have a magnetic field and are positioned to reinforce each other. Permanent magnets can further be classified into four types based on their composition:

1. Iron boron (ndfeb or nib)

2. Samarium cobalt (smco)

3. Nib and smco are the strongest types of magnets and are very difficult to demagnetize.

They are also known as rare earth magnets since their compounds come from the rare earth or lathanoid series of elements in the periodic table. The 1970s and 80s saw the development of these magnets.
