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.
Why is a magnet used in a speaker?
A magnet is used in a speaker to create a magnetic field that interacts with an electrical current, causing the speaker cone to vibrate and produce sound waves.
How does a audio speaker work?
An audio speaker works by converting electrical signals into sound waves through the movement of a diaphragm. When an electric current passes through a coil of wire in the speaker, it creates a magnetic field that interacts with a permanent magnet, causing the coil to move back and forth. This movement of the coil vibrates the diaphragm, creating sound waves that we hear as sound.
How does a magnet contribute to the functioning of a speaker?
A magnet in a speaker helps create sound by interacting with an electric current to move a diaphragm, which produces vibrations that create sound waves.
Why is there a small hole at the bottom center of a speaker magnet?
The small hole at the bottom center of a speaker magnet is to allow for the speaker to be mounted onto a pivot or axis, ensuring it remains centered and balanced when attached to a speaker enclosure or frame. It also helps in dissipating heat generated during use.
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.
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.
