Materials

A piece of paper

Mortar & pestle

Magnetic stirrer

A magnet

Some tap water

Plastic bag

Procedure:

1) Obtain as close to exactly one serving cereal as possible (by mass). Write down its mass.

2) Crush the cereal to a fine powder in the mortar and pestle, you may have to do it a little at a time. The more finely ground the cereal is, the easier it will be to get the iron.

3) Put the crushed cereal on a piece of paper. Run the magnet over crushed cereal several times, shaking the cereal around so you don't miss any particles.

4) Look for the black in iron on the magnet.

5) Collected the crushed cereal from the pieces of paper and put it on the plastic bag.

6) Cover the crushed cereal in your plastic bags with tap water.

7) Let crushed cereal desalted into the water.

8) Run the magnet inside your plastic bags several times, shaking the cereal around so you don't miss any particles.

9) Remove the magnet and collect your iron on the clean pieces of paper.(but before putting the iron on the pieces of paper u should take the mass of the paper) let it the iron dry for a minutes.

10) When the iron is dry find the mass of the iron alone. Put the piece of paper with the dry iron on top of the scale and subtract the number that the scales reads form the mass of the paper that was taken before.

11) When subtracting the mass of paper alone and the mass of the iron with the paper will give the amount of iron.

How do you take iron out of cereal?

First you want to put the cereal with some water in a blender (you can also use milk) and blend it for a while. After that let it sit in the blender for 5mins. Then pour it in a plastic or a glass cup (no metal cups) and slosh a strong magnet through it. You cannot use a refrigerator magnet for this it will not work. You must use a strong magnet to extract the iron. To get the iron off the magnet use Duct Tape!

Can it be possible that a magnet attract the iron of cereal?

It is possible yes, because the iron in the cereal 'batter' is raw elemental iron (in trace proportions) rather than a non-magnetic compound. However you'd have to blend the cereal into dust first to liberate the traces of iron. There is not nearly enough iron on one flake for the flake themselves to be attracted to a magnet.
