How does a flexible magnet work?
A flexible magnet works by attaching itself to ferromagnetic materials with the help of its magnetic field.

The flexibility of these magnets means that they can bend to suit different-shaped materials, which no other variety of magnet can do. For example, they can attach themselves to a round pillar or a flat shelf.
Magnetic pull force of a flexible magnetic sheet
The pull force of a flexible magnet attracts the ferromagnetic material to the magnet, holding it in place. The larger the pull force of the flexible magnet, the more material it can attract.
A magnet’s pull force is determined by a number of different factors; for example, how the magnet has been coated and any damage which may have occurred to the surface of the magnet.
