How does a loudspeaker use a electromagnet?
IN a loud speaker there are two magnets. one permanent magnet that always has its northpole pointing in the same direction , and one electro magnet that can change its magnetic field in direction and magnitude. IF both northpoles point into the same direciton ,the speaker cone is pushed out, if both point in opposite directions the speaker cone is pulled in. The direction and magnitude can be controlled by the current passing through the electro magnet.
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 audio speaker work?
an audio speaker works by an electro magnetic coil that vibrates when a sound wave or current is running through it. thats what makes the sound.
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 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.
Does a blender need a electro magnet to work?
Yes, AC motors generate their own magnetic field.
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" :)
How to remove magnet from a speaker?
To remove a magnet in a speaker, first detach the grill in the front of the speaker, second unscrew the speaker after that remove the speaker from the cabinet and cut the speaker cone. Lastly, gently discard the magnet from the speaker cone.
