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.
