Permanent magnets are materials where the magnetic field is generated by the internal structure of the material itself. Inside atoms and crystals you have both electrons and the nucleus of the atom.

The correct answer is 35% of cobalt.
Permanent magnets are typically made from ferromagnetic materials, such as steel alloys and cobalt.
The addition of cobalt to steel alloys can significantly enhance their magnetic properties. Alnico, a popular permanent magnet material, usually contains around 35% cobalt.
