All electric motors contain magnets- and information storage in computers is based on magnets. Electrical generators contain magnets, as do electrical Transformers. Even the charger for your iPod is based on electromagnets.
magnets attract
You could use another magnet with marked poles to determine the poles of the unmarked magnet. By observing how the unmarked magnet interacts with the marked magnet, you can identify the north and south poles of the unmarked magnet based on attraction and repulsion.

You could use magnets to push things like another magnet or you could pull metal things to it.
One could use a magnet to separate sewing pins from carpet. Using a magnet also eases pin clean up on other surfaces as well.

you could use a magnet to attract the iron if in a mixture stated, and also you could use water to disolve the Iodine and then filter out the iron
You can use a magnet to separate iron from sulfur since iron is magnetic while sulfur is not. By using the magnet to attract the iron particles, you can separate them from the sulfur.
You could do this using a magnet, Iron filings are attracted to a magnet, aluminium filings are not.Hint: magnetism, investigate the relative magnetic properties of the metals.Iron is a ferrous material, and aluminum is non-ferrous. A magnet would separate the two materials as the iron would be attracted to the magnet while the aluminum filings would not. The term ferrous basically refers to any material which contains iron.
It is not recommended to test the strength of a flywheel magnet with a screwdriver as the force exerted by the magnet could cause the screwdriver to snap towards it, potentially causing injury. It's safer to use an appropriate tool or magnet gauge to measure the strength of the magnet.
