Horseshoe magnets work by attracting ferromagnetic materials from different surfaces.
A horseshoe magnet have two magnetic poles close together, so there is a more direct path for the flux lines, which makes the magnetic field concentrated between the two magnetic poles. This means that more ferromagnetic material can be picked up.
The pull force of a horseshoe magnet attracts the ferromagnetic material to the magnet, holding it in place. The larger the pull force of the horseshoe magnet, the more material it can attract. This is because pull force refers to the limit of holding power a magnet has.A magnet’s pull force is determined by a number of different factors. See page How does a magnet work for more details.
