How does pot magnet work?

The working principle of pot magnet

A pot magnet works by attaching itself to ferromagnetic materials with the help of its magnetic field, or to non-ferromagnetic materials with the help of fittings (such as studs and threaded holes) on the top of its steel shell, industrial glue is also essential. The larger the pull force of the pot magnet, the more material it can attract.
 
The role of the steel is to lead the magnetic lines of force to the surface of the magnetic steel on the other side, making the  magnetic pull stronger.
