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 poles.
Well, honey, to separate charcoal powder and iron fillings, you can use a little technique called magnetic separation. Just grab a magnet, wave it over the mixture, and watch as those pesky iron fillings cling to the magnet while the charcoal powder minds its own business. Easy peasy lemon squeezy!

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 two poles North and South poles.
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)
