The most common uses of an electro magnet begin with the harnessing of electricity in windmills.

The electro-magnet can be switched on and pick up metal. Then the electro-magnet can be switched off and the metal will be released. A natural magnet would not release the metal.
An electro-magnet can be switched on & off - a bar magnet is 'permanent' Think of a scrap-yard. If the magnet they use to pick up huge quantities of metal were permanent, they'd have to manually remove every piece. With an electro-magnet, they simply turn the power on to pick up a load, and off when they want to release it. You can make your own electro-magnet with a battery, some wire and a large nail.
its easy! im an expert at drawing go to google images then type pics of electro magnets hope this helps!!!!!!!

An electro magnet proves that Electricity and Magnetism always co-exist in nature
An electro-magnet can be turned on and off.
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
A electro magnet is used for lifting things by the magnetic force provided by the amount of coils and the size of the battery

An electro magnet!
Electro-Magnet
Any time a magnet passes through a coil of copper wire (the electro magnet) it produces electricity. In all reallity, you don't really have an electro magnet in a generator. Since the Coil or(field) is making the electricity instead of using electricity, the electro magnet isn't really a magnet; but more like an "anti-magnet" :)
An electro-magnet would be the strongest magnet. Or the sun itself would be the strongest natural magnet.
It is a magnet or a electro-magnet. If you are trying to use it as a metal detector then you will need a really strong magnet!
Put a magnet into AC electricity
