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!!!!!!!
How do you magnetise a needle?
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
What kind of magnet is a magnet made from a steel paper clip?
If it has been magnetized by another magnet, then it is just a temporary magnet, but if it uses an electric current, then it is an electro-magnet.
Is a magnet energy?
A magnet uses the electro-magnetic force. This force also includes electricity. Very basically, it works by electrons exchanging a proton. So a magnet doesn't use energy.
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.
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 electromagnetic wave does a camera use?
it uses a radio wave as it has a big wave length. it is an electro magnet that needs to be heated to work.
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.
