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.
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 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.
