From what i have been learnt, the magnet is connected to the diaphragm (the material which covers it) of the speaker and as electric current is passed in this causes the magnet to 'Push' and 'Pull' on the diaphragm making this move resulting in sound waves being produced, these sound waves then enter your ear making you hear the noise. So the magnet helps produce the sound you hear from a speaker.

Which pole of a magnet is attracted to iron?

Any of the two poles will work. It will induce magnetism in the iron.


Inside a stereo speaker you will find two permanent magnets one on the cone and one near the cone?

The permanent magnets in a stereo speaker are used to create a magnetic field that interacts with the electrical current flowing through the voice coil attached to the speaker cone. This interaction causes the voice coil to move back and forth, pushing and pulling the cone to produce sound waves. The permanent magnet near the cone provides a stationary magnetic field, while the magnet on the cone moves with it to drive the sound production.


How do you re energize a small magnet?

When a magnet is weak, you can do three things to try to recharge it. You can rub a stronger magnet across its surface, you can stack them tightly and in the same alignment, or you can place it on something that floats in water, remove it and strike it with a hammer. These methods are not guaranteed to work.


Why there is a vibration in the speaker when a cell phone rings when it is brought near the mic?

Answer: It's called inductance. A lot of speakers use a magnet attached to a cone and place that magnet in a set of wire coils. When power is applied and changes, the magnet moves in relation to the amount of power flowing through the coils. An antenna is a very long coil meant to capture electromagnetic waves and turn them into electricity flowing back and forth in the coils. So when a cell phone (radio wave generator and receiver) produces strong enough waves, any nearby coils will pickup some of the signal and change it to electricity. here the speaker picks up the waves from the radio and moves the speaker based on the signal from the phone. If you move the phone far enough away from the speaker, it will lessen the effect (radio wave strength is related to distance inversely - (power/d^4) versus (0.distance x power).) The stronger the phone signal or the closer it is to the speaker, the higher will be the chance that the magnet will move based on the radio signal and not just the power coming from the audio product.


What happens to the bar magnet as it nears the U magnet the bar magnet will?

Move towards the U magnet so that the poles attach.

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.


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.


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.


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.


Would a speaker with a larger magnet always sounds better than a speaker with a smaller magnet?

Definitely not. Sound quality depends on so many different things.


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.


Can touching metal to a speaker magnet ruin it?

No, but placing a video tape on a speaker will ruin the tape


Why does a telephone use a magnet?

There is a magnet in the both the microphone and speaker. They change differences in air-pressure (in the microphone) to electrical pulses, and in the speaker, they cause the cone to vibrate - creating sound.


What parts do the electromagnet electric motor and speaker have in common?

A magnet


Where is a magnet located on a speaker?

At the back of the cone where the wires connect in


How could you show that a loud speaker has a magnet in it?

How does an electro magnet work in a speaker?

An electromagnet in a speaker consists of a coil of wire wrapped around a core material. When an electrical current passes through the coil, a magnetic field is produced, causing the coil to either attract or repel from a permanent magnet. This movement of the coil creates vibrations that produce sound waves, which are then amplified and projected by the speaker.
