Push magnetic sweeper being used on grass and a forklift magnetic sweeper used on a car park Magnetic sweepers work by attracting ferromagnetic materials from different surfaces.
Wonkee Donkee says "A ferromagnetic material is a term for anything attracted by a magnetic force. To be ferromagnetic it must contain a element of iron, nickel, cobalt, or gadolinium"
Magnetic force of a standard push magnetic sweeper picking up nails The pull force of the magnets within the magnetic sweeper attract the ferromagnetic material, and hold it in place. The larger the pull force of the magnetic sweeper, the more material it can attract. This is because pull force refers to the limit of holding power a magnet has.

The pull force of a magnet is not determined by its overall size. This means that a large magnet does not necessarily have a larger pull force than a small magnet.

A magnet’s pull force is determined by a number of different factors. For more information, see: How does a magnet work?
