The switch is turned on to activate the electromagnet, and metal is attracted. Turning off the switch stops the electromagnet from working, and metal is no longer attracted.
An electro magnet proves that Electricity and Magnetism always co-exist in nature
A Solenoid is an electro-magnet. It has coils of wire, usually copper. When an electric field is applied to the coils of wire, an magnetic field is generated. This magnetic field attracts a steel or iron segment on the switch and activates the switch.
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" :)
Put a magnet into AC electricity
An electro-magnet would be the strongest magnet. Or the sun itself would be the strongest natural magnet.
Increase the electric volts
