A: A speaker has a magnet and the wire is suspended in a zone by a cone whereby +/- current will make the coil move up or down moving the coil and moving the cone causing air displacement as waves of pressure that our ears can detect as sounds in our brains.

What is the purpose of the coil in a speaker?
The coil produces a magnetic field. When power is applied to the wire in the coil, the result is a magnetic charge. This magnetic charge is part of how the speaker produces sound.
Why don't my rear speakers work?
wiring problem! check wire connection form radio to speaker,if ok, check speaker coil connection, speaker coil may be loosed.
Why do speaker have magnet?
The magnet is part of the 'motor' of the sub. The coil inside the magnet has alternating current running through it. The coil acts as an electromagnet and pulls itself up or pushes itself down moving the cone of the speaker. The bigger the magnet, the stronger the magnetic field inside the speaker where the coil is.
Why are magnet used in speaker loudspeaker?
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
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 can a speaker work with holes in it?
It can work, but it will not sound good. Any deformations of the cone will "color" the sound, which will sound muddy and not clear. Eventually the speaker will die due to the voice coil dragging in the magnet because the speaker isn't moving correctly. If you have a speaker with a hole in it you should replace it.
Will the Focal 165-CA1 6.5" Car Speaker work with any system?
Yes, the Focal 165-CA1 6.5" Car Speaker will work with any system that has a 25mm voice coil and can support 60 watts.
Does a spinning coil of wire is what moves the cone in a speaker producing the sound?
False
What will be the effect if a wheel magnet received from a speaker is binded by insulated copper wire and used in place of simple inductance coil?
So already magnetic field is there in the coil but there is no change of flux inside the coil. So its basically acting as a normal metal core. But on inducing emf the direction of the current flowing in the circuit will determine the field developed by the coil but it will be either diminished or amplified depending on the direction of the induced magnetic field because of the permanent magnet.
What is the use of magnet in speakers?
Principle is electromagmnetism. When a conductor cuts magnetic field electricity is induced in the conductor (Fixed magnet). When a magnet is moved near a conductor electricity is generated in the conductor (Fixed conductor). In speakers magnet is fixed and the conductor (in the form of a coil is fixed to the back of the diaphragm) is allowed to move freely. As the coil is fixed to the diaphragm the movements of the coil is reciprocated by the movements of the diaphragm. Our voice induces varying current in the microphone and the same varying current is passed through the coil of the speaker hence it moves in the static magnetic field.
Can a silver coil make a magnetic field?
It is the flow of ELECTRICITY that makes the field in a coil. Therefore a coil of any conductor will make a field. Silver is a conductor.
Which device work by rotating a wire coil within a magnetic field to produce electric current?
generator
