Final answer:

To create a permanent magnet, a 'hard' ferromagnetic material needs to be processed in a strong magnetic field to align its internal structure, making it difficult to demagnetize.


Explanation:

A permanent magnet is made from a 'hard' ferromagnetic material that is subjected to processing in a strong magnetic field during manufacture. This process aligns the internal microcrystalline structure of the material, making it difficult to demagnetize, resulting in the creation of a permanent magnet.
