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.
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 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.
Put a magnet into AC electricity
Increase the electric volts
