the current flows to the voice coil, and at first the polarity of the current is the same as that of the speaker magnet, causing the voice coil to be pushed away from the magnet pushing the cone outward. then as the current cycles through it becomes opposite from the magnet cauing the voicecoil and cone to be pulled back in

∙ 14y agoSpeakers have very strong magnets, hence, strong magnetic fields. That's how they work, by magnetically induced vibration that creates sound.
ANSWER they do have magnetic field but they works because the ac in the coils will cause displacement

∙ 11y agoThe coil has electricity applied to it by the amplifier. This makes it an electromagnet. It reacts with the static magnetic field of the magnet and moves the attached cone as the current varies.
The magnet provides the constant magnetic field in which the varying magnetic field of the coil add to or subtracts from. The coil is connected to the speaker which varies according to the total magnetic field.

What is the loudspeaker used to produce high frequency sound called?
A tweeter.
How magnets are used in speakers?
Coils of copper wire are wrapped around the magnets. The music in your radio is converted to electrical pulses that move thru those copper wires wrapped around those magnets. The direction and strength of those electrical pulses causes them to have a magnetic reaction with the flowing electricity. This magnetic reaction is connected to a moving mechanism that is attached to your speaker cone. The way the cone moves back and forth from this coil reacting to the magnet recreates the sound coming from the radio station So the magnet is just to turn your speaker into a big electromagnet that moves like a solenoid in response to changing electrical impulses that duplicate the sound generated. The magnet has a constant field, but the coil of wire is the electromagnet but it reacts to permanent magnet. Usually the bigger the permanent magnet the bigger the sound the speaker can produce because it can generate stronger pulses from that solenoid coil that reacts to the magnet under electrical impulses
What kind of magnets are in speakers?
There is usually a large circular magnet in speakers. When an electricial current is put through the speaker cone at a certain frequency it makes the magnetic fields around the magnet change. The cone is connected to the diaphragm of the speaker which vibrates, pushing the air, creating sound waves.
Which is an electromagnetic device?
a loudspeaker
How can a magnet be used to create an electric current?
An electrical current will flow in a conductor, when a magnet is moved next to a conductor - or when the conductor is moved next to the magnet.
What is the part of a loudspeaker that vibrates to make sound?
a speaker uses a voice coil a coil copper wire and a magnet and pole to vibrate a cone
How a loudspeaker works?
A loud speaker (like other speakers) produce sound (which is actually vibrations in the air heard by the ear) with a permanent magnet and a temporary magnet in wire form that is wrapped around the permanent magnet. (or a magnet that can be turned on and off by electricity) the speaker translates the sound into a series of electrical currents and then produces the electricity to alter the temporary magnet and making the magnets vibrate and in turn vibrates the air.
How do you show that a loudspeaker has a magnet inside it?
Ask aba6iii :)!
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 loudspeaker?
we used speaker in marrige and party..............., many time speaker use as enjoy for your birthday. all people use it because it is the best things of enjoy.....
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.
In Which device is magnetic field present?
1 example is an audio loudspeaker device because a coil and magnet is used to create the sound effect.
Does iPhone have loudspeaker?
All models of the iPhone come with a speaker.
How does an electro magnet work in a speaker?
The electromagnet is used to vibrate the diaphragm of the speaker and a given rate (frequency) to produce a given sound.
How can you charge this speaker using a car charger pyle-pro-pphp159wmu-1600-watt-bluetooth-loudspeaker?

What is The symbol for a speaker?
Scroll down to related links and look at "Loudspeaker symbol and google images".
Where are the electromagnets in a loudspeaker?
Electromagnets are not used in commercially available loudspeakers due to unlinear sound reproduction, noise induced by the electromagnet current and cost. A permanent magnet with a moving coil in the magnet gap is far superior to an electromagnet considering these three parameters.
