the poles of the magnet can pick the most iron fillings. Take a magnet. Roll it into a piece of paper and scrub it in the sand, and you will find all the iron fillings connected to the poles..
The one that the field strength is stronger
Iron is one of the most common substances on earth. If the sand is rich in iron (or other magnetic particles), then it will be attracted to a magnet.
The poles.
Some minerals contain magnetite, which is atracted to magnets.

Iron filings are commonly used to demonstrate the lines of magnetic force around a magnet. When sprinkled around a magnet, the filings align themselves along the magnetic field lines, making the field visible.
A nail can be attracted to a magnet because the nail's iron material contains domains of aligned magnetic moments that can interact with the magnetic field of the magnet, causing it to be drawn towards the magnet.

Iron.
The most commonly used magnet is made of neodymium, iron, and boron (NdFeB). This type of magnet is known for its strong magnetic properties and wide range of applications.

No metals can attract a magnet. Only magnets can attract metals. (Believe me there is a difference). However the most common examples of metals which magnets would be able to pick up are Iron and Steel (steel is an alloy of Iron and Carbon)
Use a magnet. Although there are other magnetic metals, for example cobalt, most of the items you will find with a magnet will be iron-rich.
