What are the uses of electro magnet?
The most common uses of an electro magnet begin with the harnessing of electricity in windmills.
How does a sound transmit?
By electro magnet ed waves
Whyb are natural magnets noy used in cranes to lift heavy loads?
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.
What are the benefits of using an electromagnet rather than a bar manet?
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.
How do you draw an electro magnet?
its easy! im an expert at drawing go to google images then type pics of electro magnets hope this helps!!!!!!!

What does the electro magnet prove about electricity?
An electro magnet proves that Electricity and Magnetism always co-exist in nature
What magnet can be switched on and off?
An electro-magnet can be turned on and off.
When a electro magnet flows through a coil of wire wrapped around a bar of iron it makes what?
a magnetic field
How are electro magnet different from permanent magnet?
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.
Electro magnet used for?
A electro magnet is used for lifting things by the magnetic force provided by the amount of coils and the size of the battery
What are the release dates for The Wonderful Electro-Magnet - 1909?
The Wonderful Electro-Magnet - 1909 was released on: USA: 30 November 1909
What is produced whencoiled wire is spun around a magnet?
An electro magnet!
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
How are eltromagnets used in generators?
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" :)
What is the strongest type of permanent magnet?
An electro-magnet would be the strongest magnet. Or the sun itself would be the strongest natural magnet.
What is an object that attracts metal?
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!
